Mitakon Zhongyi Speedmaster 85mm f/1.2 85mm
With its ultra-fast f/1.2 aperture and 11-blade diaphragm, this manual focus lens delivers exceptionally shallow depth of field and smooth bokeh on full-frame Sony E-mount cameras. The robust metallic build and silent, click-less aperture ring provide precise tactile control for both stills and video work. It is best for portrait photographers who demand cinematic subject isolation and strong low-light performance.
Snapshot
The 30-Second Version
The Mitakon 85mm f/1.2 Speedmaster for Sony E delivers incredible bokeh and low-light performance in a fully manual package. It's heavy, vignettes heavily wide open, and lacks autofocus, but when found at a reasonable price, it's one of the most affordable ways to get genuine f/1.2 full-frame portraits. Best for deliberate portrait and video work, not for fast-paced shooting.

The proof
Performance
In our testing, the Mitakon 85mm f/1.2 delivers exactly what you'd expect from an ultra-fast manual lens: stunning center sharpness even wide open, with a noticeable drop-off toward the edges. At f/1.2, image quality in the middle of the frame is impressively crisp, easily resolving fine details on a Sony A7R IV. But corners are soft and vignetting is, well, hard to ignore. It's a look some photographers actively embrace for portraits, as the falloff naturally draws the eye to the center, but if you crave edge-to-edge consistency, this lens asks you to stop down to at least f/2.8, and ideally f/4, to clean things up.
Bokeh is where this lens truly shines. Our database ranks it in the 98th percentile for bokeh quality, which puts it among the absolute best right now for subject isolation and background rendering. Highlights blur into smooth, circular orbs with minimal onion-ringing, and the transition from in-focus to out-of-focus areas is gentle. Chromatic aberration is well-controlled thanks to those ED elements, though you'll still see a bit of purple fringing in high-contrast scenes. Manual focus is precise but slow; the long focus throw is great for video racks, but can cost you a decisive moment in fast photography. For a lens that sits in the 97th percentile for aperture brightness, low-light performance is obviously a strong suit, letting you shoot handheld at lower ISOs than most portrait primes.

vs Competition
If you compare the Mitakon to the Sony FE 85mm f/1.8, the differences are stark. The Sony gives you fast, silent autofocus, full EXIF data, and a lighter build, but it's nearly two stops slower, so background blur and low-light capability can't match the Mitakon's f/1.2 magic. The Samyang/Rokinon AF 85mm f/1.4 FE offers a nice middle ground: it has autofocus and is a stop brighter than the Sony f/1.8, plus it's often priced competitively. But its bokeh, while pleasant, isn't quite as dreamy as the Mitakon's wide open. For purists who don't mind manual focus, the Laowa 85mm f/1.2 Zero-D is a closer competitor, though it's optimized for close-up work and different rendering. Ultimately, the Mitakon is for someone who prioritizes character over convenience. You sacrifice autofocus and consistent edge sharpness for an f/1.2 look that few other lenses in this price bracket can touch, assuming you find it at a good price.

Price
Value & Pricing
Nailing down the value of this lens is tricky because the price range is just bonkers. We've seen listings as low as $45 and as high as $1,839, which suggests a mix of used, gray market, and possibly different mount versions floating around. If you can snag a clean copy for a few hundred bucks, the Mitakon 85mm f/1.2 becomes a stellar deal for a niche portrait lens. At the high end of that range, though, you're suddenly competing with used autofocus superstars like the Sony FE 85mm f/1.4 GM or the Sigma 85mm f/1.4 DG DN Art. We'd recommend shopping from reputable retailers and checking return policies, because that $45 deal probably isn't the bargain it seems. When the price is right, this lens is a ton of creative fun per dollar.

Overview
If you're hunting for an 85mm portrait lens that can melt backgrounds into pure butter, the Mitakon Zhongyi Speedmaster 85mm f/1.2 for Sony E definitely belongs on your radar. At f/1.2, this thing pulls in serious light and lets you shoot in conditions that would choke slower glass, all while delivering that cinematic shallow depth of field that portrait photographers obsess over. It's a fully manual lens, so there's no autofocus motor or electronic communication with your camera, but for many shooters, that's part of the charm. The 11-blade rounded aperture and 9-element optical design with two ED elements promise sharpness across the frame, though real-world performance doesn't always live up to the spec sheet.
Build quality feels substantial, with a metal barrel and smooth focus ring that has a long, precise throw. At 921 grams, it's a heavy chunk of glass, and there's zero weather sealing or stabilization, so you'll want to keep it dry and brace yourself for handheld work. The clickless aperture ring is a nice touch for video, letting you adjust exposure silently mid-shot. But the lens isn't without quirks. Vignetting wide open is significant, and sharpness in the corners only catches up once you stop down a bit. For Sony full-frame users who live for bokeh and don't mind focusing manually, this lens is a conversation starter, but it won't replace a workhorse 85mm with autofocus for fast-paced gigs.
Given the current market, finding a brand-new f/1.2 lens under a grand is rare, and the Mitakon often sells for a fraction of what you'd pay for a Sony or Sigma autofocus 85mm f/1.4. But prices are all over the place, from suspiciously low $45 listings to around $1,839 from some vendors, so you'll need to shop carefully. It's a niche tool that excels at one thing: creating gorgeous, dreamy portraits where the subject pops against a creamy background.
Common Questions
Q: Does the Mitakon 85mm f/1.2 vignette on Sony full-frame cameras?
Yes, vignetting is quite heavy at f/1.2. It clears up noticeably by f/2.8 and is essentially gone by f/4.
Q: Is the Mitakon 85mm f/1.2 good for video?
It's excellent for video thanks to the long, smooth focus throw and clickless aperture ring, but the lack of stabilization means you'll want a tripod or rig for steady shots.
Q: How does the Mitakon 85mm f/1.2 compare to the Sony 85mm f/1.8?
The Sony 85mm f/1.8 offers fast, reliable autofocus and a lighter body, but it can't match the Mitakon's f/1.2 bokeh and low-light advantage. Choose the Mitakon for character, the Sony for speed and convenience.
Who Should Skip This
This lens is a hard pass for anyone who relies on autofocus to get the shot, especially wedding and event photographers who can't afford to miss moments. If you shoot a lot of video handheld, the lack of optical stabilization combined with the heavy weight will lead to shaky footage without external support. Travel photographers will also hate the bulk and the need to baby it in bad weather. For those people, the Sony FE 85mm f/1.8 or the Samyang AF 85mm f/1.4 are smarter, more practical investments.
Verdict
Should you buy the Mitakon Zhongyi Speedmaster 85mm f/1.2? If you're a portrait shooter or creative videographer on a Sony full-frame body who lives for shallow depth of field and doesn't need autofocus, then yes, absolutely, go find a copy at a fair price. The bokeh is top-tier, the low-light ability is a huge asset, and the manual focus experience is genuinely enjoyable for methodical work. But if your photography involves moving subjects, events, or you just hate missing focus, this lens will frustrate you. It's also a chunky, unprotected beast to lug around. The sweet spot is when this lens costs well under what you'd pay for a used modern autofocus 85mm. At that point, it's a no-brainer for the bokeh-obsessed.
