Sony Alpha a7 IV Full Frame Mirrorless Interchangeable Lens Digital Review
The Sony a7 IV boasts a best-in-class 33MP sensor, but our data shows its autofocus and burst shooting are merely average. Is it still the ultimate hybrid camera?
The 30-Second Version
The Sony a7 IV has a best-in-class 33MP sensor (98th percentile) making it a hybrid image quality powerhouse. Its video features are strong, but autofocus and burst shooting are just average. Shop carefully—prices range from a great deal at $1,998 to a terrible one over $5,400.
Overview
The Sony a7 IV is a 33MP full-frame mirrorless camera that lands in the 98th percentile for sensor performance in our database. That means its image quality is among the absolute best you can get right now. It's a hybrid powerhouse, scoring well above average for both video (88th percentile) and stills, making it a serious all-rounder.
Sony built this camera for creators who need one body to do it all. It's got a top-tier articulating touchscreen, in-body stabilization that ranks in the 90th percentile, and 10-bit 4K video. But it's not a perfect jack-of-all-trades. Its autofocus and burst shooting scores are just middle of the pack, and it's not the camera we'd recommend for travel, where it scores a disappointing 33 out of 100.
Performance
Let's talk about where this camera shines. That 33MP BSI CMOS sensor is a standout. In real terms, you're getting incredible detail, fantastic dynamic range, and low-light performance that's a step above most competitors. The 5-axis in-body stabilization is also leading, giving you about 5.5 stops of shake correction to work with for handheld shots.
The video features are strong, too. The 4K 10-bit with Log profiles puts it well above average for serious video work. But there's a catch. While the video quality scores high, the autofocus during video lands in the 44th percentile. It's competent, but don't expect the lightning-fast subject tracking you get from Sony's higher-end cinema lines. For stills, the burst rate is a bit underwhelming at 10 fps, which falls behind many sports-oriented bodies.

Value & Pricing
Here's the wild part: the price varies by over $3,400 depending on where you look, from a reasonable $1,998 to a frankly absurd $5,430. At the lower end of that range, this camera is a fantastic value for the sensor and video quality you get. At the high end, you're getting ripped off. Always shop around. Compared to its direct rival, the Canon EOS R6 Mark II, the a7 IV often trades blows, with Sony winning on pure resolution and Canon often leading in autofocus and burst. Your choice here really depends on which set of strengths matters more to your wallet.
vs Competition
Stacked against the competition, the a7 IV carves out a clear niche. It demolishes the Nikon Z9 on price while offering a more modern sensor for hybrid shooters. Compared to the Canon R6 Mark II, you're getting 33MP vs 24MP, so the Sony wins on resolution for stills, but the Canon often has the edge in speed and AF reliability. The OM System OM-1 is in a different league for portability and burst shooting, but it's a Micro Four Thirds sensor, so the Sony's full-frame image quality is in another class entirely. For a balanced hybrid, the a7 IV's numbers are hard to beat unless you need specialist speed.

Common Questions
Q: Is the Sony a7 IV good for video?
Yes, its video capabilities score in the 88th percentile, which is well above average. It shoots 10-bit 4K with Log profiles, making it strong for color grading. However, be aware of reported overheating during long recordings, and its autofocus in video mode is just average.
Q: How does the a7 IV's autofocus compare to the Canon R6 Mark II?
Based on our percentile data, the a7 IV's autofocus (44th percentile) is about average, while the Canon R6 Mark II typically ranks higher. For fast-action photography or critical video AF, the Canon often has an edge, though the Sony's real-world performance is still very capable for most uses.
Q: Is this a good travel camera?
Not really. Our scoring specifically rates it at 33 out of 100 for travel, which is a major weak spot. This is likely due to its full-frame size, mediocre battery life (50th percentile), and lack of robust weather sealing (37th percentile). Consider a smaller, more sealed model if travel is a priority.
Who Should Skip This
Skip the Sony a7 IV if you're a sports or wildlife photographer who lives on burst mode. Its 35th percentile burst score means it lags behind most dedicated action cameras. Also, hardcore travelers should look elsewhere—its poor travel score and average build quality aren't suited for rough adventures. Finally, if you need the absolute best, most reliable autofocus for video, there are better options, as its AF ranks in the middle of the pack.
Verdict
The Sony a7 IV is a data-backed recommendation for the hybrid photographer or videographer who prioritizes image quality above all else. Its sensor and display are top of the charts, and its video features are impressive. We can't recommend it for action, sports, or as a travel companion due to its mediocre burst and AF scores. But if you want one camera that excels at both detailed stills and professional video, and you can find it near that $2,000 mark, it's a fantastic buy. Just keep the charger handy—the battery life is merely average.
