Viltrox 27mm f/1.2 27mm
Combining an f/1.2 aperture with an optical design of 15 elements, including 2 ED and 1 aspherical lens, this APS-C prime delivers sharp subject separation and strong low-light performance. Its all-metal, weather-sealed build and STM autofocus motor offer handling and reliability that exceed its price positioning. This lens is best for portrait photographers on Sony E or Fujifilm X mounts who need a fast 40.5mm-equivalent focal length with professional-grade image quality.
Snapshot
The 30-Second Version
The Viltrox 27mm f/1.2 sits in the 98th percentile for bokeh, making it one of the best portrait lenses we've tested for APS-C. You get stunning subject separation and a premium all-metal build, though the autofocus is just average and it's a heavy piece of glass. At the lower end of its $462 to $839 price range, it's an incredible value for the image quality it delivers.
Pros & Cons

The proof
Performance
Sharpness is where this lens earns its keep. The optical score sits in the 81st percentile, which is well above average for a fast prime. The 15-element, 11-group design with 2 ED elements keeps chromatic aberration in check, and the HD Nano coating does a solid job fighting flares and ghosting. But the real star of the show is the rendering. With an 11-blade diaphragm and that f/1.2 aperture, out-of-focus areas are buttery smooth. We're talking top-tier bokeh that rivals glass costing twice as much. Autofocus is a more middle-of-the-pack story, landing in the 54th percentile. The STM motor is accurate and supports eye and face detection, but it's not the fastest or quietest we've tested. For portrait work, it's perfectly adequate. For fast-paced action, you'll notice it hunting a bit more than a top-tier first-party lens.

vs Competition
Stacked against the Sigma 16-300mm or Tamron 18-300mm superzooms, this Viltrox is a completely different animal. Those lenses prioritize versatility, scoring much higher for travel, while the Viltrox is a specialized tool that sacrifices zoom range for outright image quality and aperture. The Meike 55mm f/1.4 is a closer competitor in spirit, but it can't touch the Viltrox's f/1.2 light gathering or bokeh quality. If you need one lens that does everything, look elsewhere. If you want a dedicated portrait prime that creates images with a look the zooms simply can't replicate, the Viltrox is in a different league. The Nikon Z 28-400mm offers incredible range but at f/4-8, you're giving up several stops of light and that shallow depth of field magic.

Price
Value & Pricing
Pricing on this lens is a bit of a rollercoaster. We're seeing it listed anywhere from $462 to $839 across different vendors, which is a massive $377 spread. At the low end, this lens is an absolute steal. You're getting f/1.2 optics and a weather-sealed metal build for less than many f/1.4 alternatives. At the high end, it's a tougher sell and starts bumping up against used first-party glass. Shop around and don't pay the premium. The Amazon listing is where we're seeing the best deals, so that's your starting point.

Overview
The Viltrox 27mm f/1.2 is a portrait monster that lands in the 98th percentile for both aperture and bokeh in our database. That f/1.2 max aperture isn't just a spec sheet flex, it translates to genuinely stunning subject separation and low-light capability that's hard to find at this price. The 40.5mm full-frame equivalent field of view on APS-C hits a sweet spot that's tight enough for flattering portraits but wide enough to tell a bit of an environmental story. It's not a small lens at 605g, but the all-metal build feels substantial in hand, and the weather sealing means you don't have to panic if a shoot gets a little damp.
Common Questions
Q: Will this lens work on my full-frame Sony camera?
Technically yes, but we wouldn't recommend it. This is an APS-C lens, so on a full-frame body like the A7C II, you'll either get heavy vignetting or be forced into crop mode, throwing away a lot of your sensor's resolution. You're better off with a lens designed for full-frame coverage.
Q: Is this lens too heavy for a smaller Fujifilm body like the X-T50?
It's not too heavy to mount or use safely, but at 605g, it will feel front-heavy on a compact body. The X-T50 with an added grip handles it fine, but it's not a balanced, one-handed setup. Expect to support the lens with your left hand, which is good practice anyway.
Q: How does the autofocus perform for video work?
The STM motor is accurate and supports face and eye detection, which is great for talking-head shots. But it's not the fastest in our database, landing in the 54th percentile for AF performance. Focus pulls aren't lightning quick, and the lack of optical stabilization means you'll want a gimbal or a very steady hand for smooth footage.
Who Should Skip This
Travel and video shooters should look elsewhere. The travel score is a disappointing 47.2 out of 100, and it's easy to see why. The 605g weight and lack of zoom make it a poor choice for a walkaround lens. Video folks will miss optical stabilization, and the autofocus, while accurate, isn't snappy enough for fast-paced run-and-gun work. If you need a versatile all-rounder, one of the superzooms in this comparison set will serve you much better, even if you sacrifice that gorgeous f/1.2 aperture.
Verdict
The Viltrox 27mm f/1.2 is a specialized tool that absolutely nails its intended purpose. It's a portrait lens first and foremost, and in that role, it delivers results that land in the top tier of our database. The image quality and bokeh are genuinely impressive, and the build quality inspires confidence. Just know what you're signing up for. This isn't a travel lens, it's not a video workhorse, and the autofocus won't set any speed records. But if you're building an APS-C kit and want that f/1.2 look without selling a kidney, this is one of the best options on the market right now.
