Newly developed 33.0‑MP1 back-illuminated CMOS image sensorThe full-frame Exmor R™ CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p2. The sensor also provides improved colour reproducibility, low-noise performance at all sensitivities, 15-stop3 dynamic range on stills and increased AF precision and focal stability.
BIONZ XR™ image processor for up to 8x4 processing speedThe BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x4 increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimize processing latency, for greatly increased movie and still processing power. User interface, network and file management processing is distributed in order to deliver fast response regardless of real-time processing load.
Beautiful image rendering with low noiseVisible benefits of the powerful new 33.0‑MP1 sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery and better colour reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.
Smoother gradation rendering with 10-bit HEIF recordingThe α7 IV offers HEIF (High Efficiency Image File)5 still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects and the use of 10-bit depth minimizes degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV via an HDMI connection to display images with an extraordinarily wide dynamic range.
4K 60p2 recording, 4:2:2 10-bit recordingThe α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p2 recording and when recording 4K movies at 30p, full-frame 7K6 oversampling7 produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS™ file format8 provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.
Set the mood, in-camera, with Creative LookBroaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies and live streaming and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting.
Beautiful colour expression made simple, with S-Cinetone™The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6 and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin colour, plus soft colours and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing.
S-Log for colour matching with professional video equipmentThe α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops9 of dynamic range. The S-Gamut3 and S-Gamut3.Cine colour gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800 and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra-low noise.
Soft Skin Effect for bright and beautiful skin appearanceThe built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available10, so you can adjust the degree of the effect as you wish.
Optical 5-axis in-body image stabilization for 5.5-step11 compensationThe α7 IV's high-precision stabilization unit and gyro sensors work with stabilization algorithms to achieve up to 5.5 steps11 of shutter-speed compensation, to maximize the performance of the camera's 33.0‑MP1 sensor. This in-body stabilization allows effective use with a wide range of lenses. The live monitor view shows the stabilized still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens and it can be used in conjunction with the MF Assist and Focus Magnifier features.
Hand-held movie shooting with Active Mode12Active Mode12 uses the camera's stabilization unit, gyro sensors and sophisticated algorithms for highly effective in-camera optical image stabilization during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilization in all formats13, including 4K, without compromising the α7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilization can be applied for ultra-smooth shots using Catalyst Browse/Prepare software14.
Buffer memory supports continuous shooting and recordingBoth the mechanical and electronic shutters allow continuous shooting at up to 10 fps15 with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 80016 uncompressed RAW+JPEG frames (more than 1,600 altogether) or more than 1,000 compressed RAW+JPEG frames (more than 2,000 altogether, up to a full memory card)17. Increased processing power also allows you to change menu settings even while data is being written to the memory card.
Fast Hybrid AF with improved speed, precision and trackingUsing a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely, even on small subjects or on people posed in front of a night-time background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 75918 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analyzed in real time by the latest powerful processing engine to achieve the AF system's impressive results.
AI-based Real-time Eye AF and Real-time Tracking19The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy20, while faster image processing yields higher accuracy when the subject is looking up, down or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.
Bird mode for Real-time Eye AF, now available in moviesThe Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.
AF control through touch operationTouch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots.
AF Assist for seamless transitions to manual focus21The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject.
Visualize depth of field during movie shoots with Focus Map22The new Focus Map22 overlays focus information onto a live real-time display to show which areas are in or out of focus. Being able to clearly visualize depth of field in this way makes it easier to quickly set up your ideal focus point and depth of field during rehearsal. As a result, you can use the camera's excellent video definition and fast lenses to create impressive shots with shallow depth of field.
Breathing Compensation23 for consistent angle of view when focusingFor the first time in the α series, the α7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus24. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilization to shoot stable, consistent imagery.
Still/Movie/S&Q dial for quick access to hybrid capabilitiesBefitting the α7 IV's status as a true hybrid camera, it comes equipped with a dedicated Still/Movie/S&Q dial to instantly switch between movies and stills. The dial switches the menus, functions and custom settings of various controls between still and movie mode and settings such as aperture and shutter speed are also maintained separately for stills and movies. S&Q mode can also be selected, for fast access to slow-motion or quick-motion shooting.
The latest mode-specific menus and customizable Rear dial RThe α7 IV's menus are specific to either stills or movies and for easier navigation menus are configured to show three levels of hierarchy at once. Separate functions for stills and for movies can be assigned to various buttons and dials, including the new, freely customizable Rear dial R. With controls tailored to whichever shooting mode you are currently using, the flexible access provided by the Rear dial R contributes to greatly enhanced still- and movie-shooting efficiency.
Vari-angle LCD monitor for greater freedom when shootingThe large, side-opening 3.0-type 1.03-megadot25 touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting or very low ground-level shots.
3.68‑megadot25 high-definition Quad-VGA OLED viewfinderThe α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3 ° FOV and a 23‑mm high eyepoint. With high resolution, improved electronic viewfinder image quality and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.
Communication features for easy sharing and distributionThe α7 IV is equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5‑GHz26 band in addition to the 2.4‑GHz27 band, for fast data transfer. Background FTP transfer of files can be set to occur automatically while shooting continues and a USB Type-C® connector supports fast SuperSpeed USB 10‑Gbps (USB 3.2 Gen 2) data transfer.
Instant real-time live streaming via USB connectionLive streaming is as easy as connecting to a computer through a USB connection and you can choose from four different output formats, including high-resolution 4K video28. You can select whichever configuration is best for current network conditions and the devices used and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.
High-capacity Z batteries and USB Power Delivery29The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies29 and AC adapters. Battery drain can be minimized by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD30 can be connected to the camera's USB Type-C® port, for extended recording.
Heat managementTo allow extended continuous recording, efficient heat dissipation is provided by Sony's proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilization while heat is efficiently dissipated.
Dual media slots, with CFexpress Type A supportDual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards31 and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate 4K movie recording.
Reliable, robust engineeringWe have improved the dust and moisture resistance32 of the α7 IV to provide outstanding reliability, even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover and internal frame provides excellent durability.
Consideration for the environment and resource conservationSony's "Road to Zero" environmental plan was launched in 2010 with the ultimate goal of achieving a zero environmental footprint. Currently, nearly all plastic packaging materials for the α7 IV are recycled. Recyclable materials are also used for camera bodies whenever possible, reducing environmental burden without compromising functionality. While retaining state-of-the-art performance, we aim to further reduce energy and resource consumption to reduce the burden on the environment.
Imaging Edge Desktop™ / Imaging Edge Mobile™Expand your creative horizons with Imaging Edge Desktop33 and Imaging Edge Mobile34. The Imaging Edge Desktop PC application lets you control and monitor shoots directly from your PC screen, preview photos and develop RAW/HEIF data into high-quality photos for delivery. Imaging Edge Mobile applications use the Wi-Fi and Bluetooth® functionality of the α7 IV to provide a wide variety of convenient shooting and sharing functions.

α7 IV full-frame hybrid camera
The latest sensor, processing engine and AI-based autofocus work in tandem with cutting-edge still-photography and movie-making technology to create a fresh, dynamic imaging experience. The α7 IV is the ideal hybrid, providing breathtaking still and movie imagery, along with flexible connectivity for on-the-spot transmission of your images.
Newly developed 33.0‑MP1 back-illuminated CMOS image sensorThe full-frame Exmor R™ CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p2. The sensor also provides improved colour reproducibility, low-noise performance at all sensitivities, 15-stop3 dynamic range on stills and increased AF precision and focal stability.
BIONZ XR™ image processor for up to 8x4 processing speedThe BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x4 increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimize processing latency, for greatly increased movie and still processing power. User interface, network and file management processing is distributed in order to deliver fast response regardless of real-time processing load.
Beautiful image rendering with low noiseVisible benefits of the powerful new 33.0‑MP1 sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery and better colour reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.
Smoother gradation rendering with 10-bit HEIF recordingThe α7 IV offers HEIF (High Efficiency Image File)5 still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects and the use of 10-bit depth minimizes degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV via an HDMI connection to display images with an extraordinarily wide dynamic range.
4K 60p2 recording, 4:2:2 10-bit recordingThe α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p2 recording and when recording 4K movies at 30p, full-frame 7K6 oversampling7 produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS™ file format8 provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.
Set the mood, in-camera, with Creative LookBroaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies and live streaming and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting.
Beautiful colour expression made simple, with S-Cinetone™The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6 and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin colour, plus soft colours and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing.
S-Log for colour matching with professional video equipmentThe α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops9 of dynamic range. The S-Gamut3 and S-Gamut3.Cine colour gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800 and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra-low noise.
Soft Skin Effect for bright and beautiful skin appearanceThe built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available10, so you can adjust the degree of the effect as you wish.
Optical 5-axis in-body image stabilization for 5.5-step11 compensationThe α7 IV's high-precision stabilization unit and gyro sensors work with stabilization algorithms to achieve up to 5.5 steps11 of shutter-speed compensation, to maximize the performance of the camera's 33.0‑MP1 sensor. This in-body stabilization allows effective use with a wide range of lenses. The live monitor view shows the stabilized still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens and it can be used in conjunction with the MF Assist and Focus Magnifier features.
Hand-held movie shooting with Active Mode12Active Mode12 uses the camera's stabilization unit, gyro sensors and sophisticated algorithms for highly effective in-camera optical image stabilization during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilization in all formats13, including 4K, without compromising the α7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilization can be applied for ultra-smooth shots using Catalyst Browse/Prepare software14.
Buffer memory supports continuous shooting and recordingBoth the mechanical and electronic shutters allow continuous shooting at up to 10 fps15 with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 80016 uncompressed RAW+JPEG frames (more than 1,600 altogether) or more than 1,000 compressed RAW+JPEG frames (more than 2,000 altogether, up to a full memory card)17. Increased processing power also allows you to change menu settings even while data is being written to the memory card.
Fast Hybrid AF with improved speed, precision and trackingUsing a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely, even on small subjects or on people posed in front of a night-time background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 75918 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analyzed in real time by the latest powerful processing engine to achieve the AF system's impressive results.
AI-based Real-time Eye AF and Real-time Tracking19The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy20, while faster image processing yields higher accuracy when the subject is looking up, down or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.
Bird mode for Real-time Eye AF, now available in moviesThe Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.
AF control through touch operationTouch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots.
AF Assist for seamless transitions to manual focus21The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject.
Visualize depth of field during movie shoots with Focus Map22The new Focus Map22 overlays focus information onto a live real-time display to show which areas are in or out of focus. Being able to clearly visualize depth of field in this way makes it easier to quickly set up your ideal focus point and depth of field during rehearsal. As a result, you can use the camera's excellent video definition and fast lenses to create impressive shots with shallow depth of field.
Breathing Compensation23 for consistent angle of view when focusingFor the first time in the α series, the α7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus24. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilization to shoot stable, consistent imagery.
Still/Movie/S&Q dial for quick access to hybrid capabilitiesBefitting the α7 IV's status as a true hybrid camera, it comes equipped with a dedicated Still/Movie/S&Q dial to instantly switch between movies and stills. The dial switches the menus, functions and custom settings of various controls between still and movie mode and settings such as aperture and shutter speed are also maintained separately for stills and movies. S&Q mode can also be selected, for fast access to slow-motion or quick-motion shooting.
The latest mode-specific menus and customizable Rear dial RThe α7 IV's menus are specific to either stills or movies and for easier navigation menus are configured to show three levels of hierarchy at once. Separate functions for stills and for movies can be assigned to various buttons and dials, including the new, freely customizable Rear dial R. With controls tailored to whichever shooting mode you are currently using, the flexible access provided by the Rear dial R contributes to greatly enhanced still- and movie-shooting efficiency.
Vari-angle LCD monitor for greater freedom when shootingThe large, side-opening 3.0-type 1.03-megadot25 touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting or very low ground-level shots.
3.68‑megadot25 high-definition Quad-VGA OLED viewfinderThe α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3 ° FOV and a 23‑mm high eyepoint. With high resolution, improved electronic viewfinder image quality and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.
Communication features for easy sharing and distributionThe α7 IV is equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5‑GHz26 band in addition to the 2.4‑GHz27 band, for fast data transfer. Background FTP transfer of files can be set to occur automatically while shooting continues and a USB Type-C® connector supports fast SuperSpeed USB 10‑Gbps (USB 3.2 Gen 2) data transfer.
Instant real-time live streaming via USB connectionLive streaming is as easy as connecting to a computer through a USB connection and you can choose from four different output formats, including high-resolution 4K video28. You can select whichever configuration is best for current network conditions and the devices used and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.
High-capacity Z batteries and USB Power Delivery29The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies29 and AC adapters. Battery drain can be minimized by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD30 can be connected to the camera's USB Type-C® port, for extended recording.
Heat managementTo allow extended continuous recording, efficient heat dissipation is provided by Sony's proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilization while heat is efficiently dissipated.
Dual media slots, with CFexpress Type A supportDual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards31 and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate 4K movie recording.
Reliable, robust engineeringWe have improved the dust and moisture resistance32 of the α7 IV to provide outstanding reliability, even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover and internal frame provides excellent durability.
Consideration for the environment and resource conservationSony's "Road to Zero" environmental plan was launched in 2010 with the ultimate goal of achieving a zero environmental footprint. Currently, nearly all plastic packaging materials for the α7 IV are recycled. Recyclable materials are also used for camera bodies whenever possible, reducing environmental burden without compromising functionality. While retaining state-of-the-art performance, we aim to further reduce energy and resource consumption to reduce the burden on the environment.
Imaging Edge Desktop™ / Imaging Edge Mobile™Expand your creative horizons with Imaging Edge Desktop33 and Imaging Edge Mobile34. The Imaging Edge Desktop PC application lets you control and monitor shoots directly from your PC screen, preview photos and develop RAW/HEIF data into high-quality photos for delivery. Imaging Edge Mobile applications use the Wi-Fi and Bluetooth® functionality of the α7 IV to provide a wide variety of convenient shooting and sharing functions.

En 30 secondes
Le Sony A7 IV combine un capteur 33 MP détaillé et un autofocus quasi parfait dans un boîtier tropicalisé. La vidéo 4K 60p 10 bits est excellente en courtes séquences, mais la tendance à chauffer bride les enregistrements longs. Le meilleur prix se situe autour de 1 859 $ chez Newegg. La recommandation est claire : foncez si vous êtes créateur hybride, restez sur un vrai caméscope ou un boîtier orienté rafale si vous avez des besoins très spécifiques.
Aperçu
Sony a redessiné le paysage des hybrides avec l'Alpha 7 IV. Ce boîtier, c'est un peu le couteau suisse du plein format : 33 mégapixels, une rafale à 10 i/s, une vidéo 4K 60p 10 bits 4:2:2 avec le color profile S-Cinetone directement embarqué. On l'adresse aux créateurs hybrides, aux vidéastes YouTube, aux photographes de mariage qui jonglent entre photo et rushs vidéo et qui veulent un seul appareil pour tout gérer. Le kit avec le 28-70mm zoom est un bon point de départ, mais c'est surtout le boîtier qui retient l'attention.
Le positionnement est malin : 33 MP, c'est pile entre le high-res de l'A7R et la définition plus modeste d'un A7 III, tout en offrant un autofocus qui fait partie des tout meilleurs du marché, avec 759 points et détection des sujets, des yeux, des animaux. La construction respire la qualité, tropicalisée et taillée dans du magnésium, à 658 grammes. Bref, ça sent le boîtier qui va rester vissé à la main pendant des années.
Mais il y a un "mais". Sony a refourgué un traitement antireflet d'écran correct, mais pas le top, et surtout, la vidéo en 4K poussée peut faire transpirer le boîtier au sens propre. Si vous filmez une interview de 40 minutes en plein soleil, attendez-vous à un message de surchauffe. Rien de rédhibitoire pour des clips courts, mais ça calme l'enthousiasme du "full hybrid".
Performances
Le capteur Exmor R rétroéclairé, couplé au nouveau processeur BIONZ XR, envoie des images avec une dynamique qui tient la route et une montée en ISO propre jusqu'à 12800 sans souci. L'autofocus, c'est juste un régal : il accroche l'œil humain ou animal quasi instantanément et ne lâche pas, même quand le sujet bouge vite. L'EVF de 3,69 millions de points est confortable, et la stabilisation IBIS corrige pas mal de tremblements à main levée en photo. En rafale mécanique, 10 i/s c'est bien, mais ça reste dans le milieu du panier face aux foudres de guerre comme le Canon R6 Mark III ou l'X-H2S. Pour du sport ou du reportage nerveux, le buffer peut sembler un peu juste.
Côté vidéo, le 4K 30p issu d'un suréchantillonnage 7K est super piqué, sans pixel binning. Le 4K 60p découpe dans le capteur en Super 35, mais la qualité 10 bits 4:2:2 en interne est sérieuse pour de l'étalonnage. Le S-Cinetone offre des couleurs prêtes à diffuser, et le Log S-Log3 donne de la latitude en post. Le refroidissement passif fait son job pour des prises de 20 minutes, mais au-delà, surtout avec des hauts ISO ou en extérieur, l'overheating peut interrompre l'enregistrement. C'est le talon d'Achille et ça empêche ce boîtier de boxer avec un vrai caméscope pour les longs tournages.
Avantages et inconvénients
Pros
- Autofocus ultra-réactif et précis, même en basse lumière, avec détection œil/animal fiable 96th
- Qualité d'image photo excellente, capteur 33 MP offrant une marge de recadrage appréciable 96th
- Construction tropicalisée robuste, boîtier en magnésium et joints d'étanchéité présents 94th
- Vidéo 4K 60p 10 bits 4:2:2 en interne, avec S-Cinetone et S-Log3 exploitables directement 93th
- Très bonne autonomie pour un hybride (520 vues CIPA, mais souvent bien plus en usage réel)
Cons
- Surchauffe en vidéo 4K 60p prolongée, arrêts possibles après 25-30 minutes sans refroidissement actif
- Rafale mécanique limitée à 10 i/s, buffer pas taillé pour une rafale soutenue sur plusieurs secondes
- Écran tactile aux fonctionnalités basiques, pas de navigation complète dans les menus
- Le port CFexpress Type A est onéreux et moins répandu que les formats CFe Type B
- Zoom de kit 28-70mm correct sans plus, pas assez piqué pour exploiter tout le potentiel du capteur

Rapport qualité-prix
Le tarif de l'A7 IV fluctue énormément selon les revendeurs. On a vu des écarts allant de 1 859 $ à… plus de 462 000 $ (ne cherchez pas, c'est probablement une erreur de listing). Dans les faits, le prix réaliste tourne autour de 1 859 $ pour le kit chez Newegg, ce qui est franchement agressif pour un plein format aussi abouti. À ce montant, vous avez un boîtier quasi pro avec une qualité d'image et un autofocus de très haut niveau, plus que compétitif face à des Canon EOS R6 Mark III ou Nikon Z6 III souvent plus chers à fiche technique équivalente.
En neuf, le rapport qualité/prix est donc très solide si vous chopez l'offre la plus basse sur Newegg. D'autres vendeurs comme Best Buy ou Amazon proposent des tarifs similaires, parfois avec un bundle. Si votre budget est serré, il n'y a pas trente-six alternatives en plein format récent qui cochent autant de cases pour ce prix.
Face à la concurrence
Le Canon EOS R6 Mark III lui colle aux basques : il a l'avantage d'une rafale bien plus rapide (40 i/s électronique) et une meilleure gestion de la chauffe en vidéo, mais son capteur 24 MP cède un peu de résolution et son système AF, bien que performant, reste un soupçon moins magique sur les sujets erratiques que le Sony. Pour le photographe pur sport, le Canon peut séduire, pour le créateur hybride qui retouche et recadre souvent, le Sony tient la corde.
Face au Panasonic LUMIX GH7, le match est différent : le GH7, en micro 4/3, ne joue pas du tout dans la même cour en photo plein format, mais son refroidissement actif en fait une bête de vidéo sans limite de durée. Si vous faites des interviews fleuves ou des directs prolongés, le GH7 est plus fiable. Le Sony, lui, garde l'avantage du grand capteur et de la faible profondeur de champ. Le Nikon Z9, étalon absolu à 5 500 $, est hors budget pour l'immense majorité des acheteurs de cet A7 IV, et les Fujifilm X-H2S ou OM-1 Mark II restent en APS-C/micro 4/3 avec des performances sportives mais un rendu d'image moins polyvalent en basse lumière.

Questions fréquentes
Q: Est-ce que l'écran est tactile et peut-on s'en servir pour les menus ?
L'écran LCD de 3 pouces est bien tactile et orientable latéralement, idéal pour le vlogging. En revanche, la navigation tactile dans les menus est limitée : on peut sélectionner le point AF et feuilleter les images, mais la configuration avancée reste dédiée à la molette et aux boutons physiques.
Q: Quelle monture d'objectif utilise ce boîtier ?
Le Sony A7 IV utilise la monture E (Sony FE), compatible avec une très vaste gamme d'optiques allant des focales fixes lumineuses aux zooms haut de gamme G Master. Vous pouvez aussi monter des objectifs A-mount via une bague d'adaptation LA-EA5.
Q: Peut-on brancher un micro externe et un casque pour monitorer le son ?
Oui, le boîtier dispose d'une entrée micro jack 3,5 mm et d'une sortie casque pour contrôler l'audio en temps réel. Si vous avez besoin d'entrées XLR professionnelles, vous pouvez ajouter le kit adaptateur XLR-K3M via la griffe Multi Interface.
Q: La surchauffe est-elle vraiment un problème en vidéo ?
C'est le principal point faible. En 4K 60p 10 bits, le boîtier peut afficher un avertissement de surchauffe après environ 25 à 30 minutes d'enregistrement continu, surtout par temps chaud. Régler le paramètre « Temp. arrêt auto » sur « Élevée » repousse un peu la limite, mais pour des prises très longues, un enregistreur externe ou un boîtier avec refroidissement actif comme le Sony FX3 sera bien plus fiable.
À qui ce produit ne convient pas
Les vidéastes qui filment des conférences entières, des cérémonies sans coupure ou des directs de plusieurs heures devraient passer leur chemin. L'appareil chauffe et s'arrête, c'est mécanique. Un Sony FX3 avec son ventilateur intégré ou un Panasonic GH7 au refroidissement actif sont bien mieux adaptés. Les photographes sportifs exigeant une rafale soutenue d'au moins 20 i/s avec un buffer profond seront aussi frustrés : le Canon EOS R6 Mark III ou le Sony A9 restent plus pertinents. Et si votre unique obsession, c'est la photographie produit ultra-détaillée avec besoin d'un mode pixel shift haute résolution, tournez-vous plutôt vers un Sony A7R V.
Verdict
Pour le créateur qui alterne entre photos de portrait, de rue et vidéos YouTube bien punchy, l'Alpha 7 IV est probablement le meilleur achat actuel. Il excelle dans presque tous les domaines sans vous ruiner, avec un autofocus que vous n'aurez plus besoin de paramétrer tant il fait le job. Si vous montez un setup hybride et voulez vous simplifier la vie, vous prenez celui-là, une optique lumineuse, et vous êtes paré pour 90 % des situations.
Mais si votre activité est polarisée, il faut être lucide. Le vidéaste de mariage qui tourne des cérémonies entières en continu ou le reporter animalier qui mitraille 40 images par seconde trouveront rapidement les limites de l'A7 IV et regarderont à juste titre vers des boîtiers plus spécialisés. Pour tous les autres, c'est un choix facile à recommander.
