The Viltrox 25mm f/1.7 Is Shockingly Sharp for What It Costs

Picking a fast prime lens for Fuji's APS-C system means navigating a crowded market, and the sub-$200 category doesn't usually inspire much confidence. This might be an exception.

Coming to you from Mitch Lally, this hands-on video covers Lally's real-world experience shooting the Viltrox 25mm f/1.7 on the Fujifilm X-E5 over the course of about a month, including fashion and test shoots where it served as his main lens. At 25mm on APS-C, you're looking at roughly a 38mm equivalent, which puts it in a slightly unusual but useful position between Fuji's 23mm f/1.4 and 23mm f/2. Lally was shooting it wide open regularly, and the center sharpness held up well enough that he could lean on the X-E5's crop modes without things falling apart.

Where it gets interesting is the autofocus comparison. Lally pits the Viltrox directly against the Fujifilm 27mm f/2.8 pancake, and the difference in focus behavior is significant enough that he does an on-camera audio comparison so you can hear the motor noise side by side. The Viltrox acquires focus more confidently and holds it with eye tracking in a way the 27mm doesn't. There are real tradeoffs to acknowledge, though: no weather-sealing, no aperture ring, a plastic build that doesn't match Fuji's aesthetic, and some light leak behavior when shooting directly into the sun without a hood.

The no-aperture-ring issue is worth thinking about if you're used to Fuji's physical controls. On the X-E5, Lally's front and rear dials handle ISO and shutter speed, so switching to aperture control means clicking into the front dial, which adds a step he wasn't used to. It's a genuine annoyance rather than a dealbreaker, and he's honest about the tradeoff. The light leak situation is similar: not a flaw he'd dismiss outright, but something you'd want to understand going in. Whether either of those things bothers you depends entirely on how you shoot.

Check out the video above for the full rundown from Lally, including the side-by-side autofocus audio comparison and sample images from his recent portrait and fashion shoots.
