Fujifilm VILTROX 25mm F1.7 f/1.7 AF Lens for Fuji X Mount, Review

The Viltrox 25mm F1.7 is a lens that knows exactly what it wants to be: a sharp, fast portrait prime for your Fujifilm camera. At 25mm on an APS-C sensor, you're getting a classic 38mm full-frame equivalent field of view. That's a sweet spot for environmental portraits and everyday shooting. And with an f/1.7 maximum aperture, it's ready for low light. The specs are solid, with 12 elements in 10 groups, including one ED and two aspherical elements to keep things sharp. It's not trying to be everything to everyone, and that's okay.

This lens shines where it counts. Its autofocus performance lands in the 96th percentile, which is seriously impressive for a third-party lens. The STM motor is quick and quiet, making it a great choice for video work, which is reflected in its 94.7/100 score for cinema. Its macro capability is its absolute standout, hitting the 97th percentile. You can focus as close as 25cm, which is fantastic for detail shots. The built-in stabilization, sitting in the 89th percentile, gives you a real edge in handheld shooting, especially in those low-light situations where f/1.7 already helps.

At around $176, the value proposition here is pretty clear. You're getting near-professional level autofocus and class-leading macro performance for less than many first-party options. The inclusion of stabilization at this price point is a major bonus that many competitors lack. While the build feels a bit budget, the optical and focusing performance punch well above the price tag. For a Fuji shooter looking for a dedicated portrait or detail lens without breaking the bank, it's hard to argue with the numbers.

Compared to the Fujifilm XF 23mm f/2 WR, you're trading weather sealing and a slightly wider field of view for a faster aperture (f/1.7 vs f/2), much better macro ability, and built-in stabilization, all for less money. Against the Viltrox 35mm f/1.7 for Z-mount, you're looking at a similar aperture but a tighter focal length (a 52mm equivalent), and you lose the stabilization. The real competition might be manual focus lenses like the Meike 55mm f/1.8, which offers a different look but requires you to give up that fantastic 96th-percentile autofocus. If AF and close-focus are priorities, this Viltrox 25mm is in a league of its own at this price.

If you shoot portraits, details, or video on your Fujifilm camera and need reliable autofocus, this lens is a no-brainer. The data doesn't lie: its AF and macro scores are elite. You'll miss weather sealing and the build is merely average, but for pure performance per dollar, it's a standout. Just know that its 38mm equivalent field of view makes it a specialist. If you need a single lens for everything, look elsewhere. But if you want a sharp, fast, and incredibly capable tool for specific jobs, grab it.
