Viltrox AF 27mm F1.2 Pro Review: An F1.2 Everyday Prime for APS-C at Around $550
On an APS-C camera, 27mm gives about the same view as a 40mm lens on full frame. It’s a natural, everyday focal length, a little wider than a “normal” 50mm, good for street, travel and environmental portraits. The Viltrox AF 27mm F1.2 Pro gives you that view at f/1.2, for around $550.
Viltrox released the Fujifilm X-mount version first, in 2023, then a Sony E-mount version. Both belong to Viltrox’s Pro line, which uses better build and weather sealing than its budget lenses.
It’s another sign of how far Chinese lens makers have come in the last five years.
Video review: Dustin Abbott
Sharp at f/1.2
It’s very sharp across the frame, even wide open. That’s unusual for an f/1.2 lens at this price. Chromatic aberration, coma and flare are well controlled, so it handles night streets and point lights cleanly.
Bokeh is smooth, and highlights turn nicely round once you stop down a little.
Close focus is 28 centimeters, for 0.15x magnification. Fine for details and food.
Pro-level build
The barrel is solid, with a proper aperture ring that has an A position past f/16, a click/de-click switch for video, an AF/MF switch and a custom focus-hold button. There’s a USB-C port in the mount for firmware updates, and the lens is sealed against dust and moisture.
Autofocus uses a stepping motor. It’s fast, accurate and quiet, with strong eye tracking on current Sony and Fuji bodies. Reviewers found it works especially well on Sony.
The downsides
Size and weight. It weighs about 570 grams with a 67mm filter. For an APS-C prime that’s big; on a small body like the Fujifilm X-M5 or Sony ZV-E10 II it dominates the camera.
Focus breathing is noticeable, so the frame shifts slightly when you pull focus in video.
Vignetting is strong wide open, though easy to correct.
The plastic hood can work loose.
Who should buy it
Street, travel and documentary shooters on Sony or Fuji APS-C who want one fast everyday prime. Low-light shooters, wedding photographers who want a candid lens, and anyone who wants full-frame-style background blur from a crop sensor.
If you want something smaller, Fuji’s XF 27mm f/2.8 pancake or the Sigma 23mm f/1.4 are lighter options. If you want maximum light and the most blur at this field of view, the Viltrox is the one to get, and it pairs well with the Viltrox 75mm f/1.2 Pro for portraits.
