Viltrox AF 35mm f/1.7 XF STM ASPH ED IF Autofocus APS-C Lens for FUJIFILM X-Mount, Black {52}

Viltrox 35mm f/1.7: compact APS-C prime with native X-Mount AF

At 180 grams and 56mm long, this lens sits on a Fujifilm X body without throwing the balance off, a real consideration for shooters who carry their kit all day. The 35mm focal length hits roughly 53mm equivalent on APS-C, landing squarely in natural-perspective territory. a f/1.7 maximum aperture gives you genuine low-light capability and subject separation without climbing into the size and cost of faster glass.

The optical formula runs 11 elements across 9 groups, with one ED element, one aspherical element, and two high-refractive elements working together to manage chromatic aberration and field curvature. The STM autofocus motor keeps things quiet during video and responsive for stills, and full-time manual override means you can nudge focus without switching modes. Nine diaphragm blades round out the package, producing smoother out-of-focus rendering at wider apertures. Minimum focus sits at 0.33 meters, yielding a 0.13x maximum magnification, enough for close environmental detail without being a dedicated macro. A 52mm filter thread keeps accessories affordable.

Who It's For

Street photographers working Fujifilm X bodies will appreciate the near-silent STM motor and a form factor that doesn't telegraph the camera. Documentary and travel shooters get a 53mm-equivalent field of view that reads as neutral, paired with f/1.7 for dim interiors and evening work without flash. Portrait photographers shooting environmental work at closer distances benefit from the 0.33-meter minimum focus, which allows tighter framing of faces with context. Video shooters using X-series cameras get a quiet focus motor that won't bleed into on-camera audio.

FAQ

What's the equivalent focal length on a Fujifilm X camera?

35mm translates to roughly 53mm equivalent on APS-C, placing it in natural perspective territory - wider than standard 50mm but narrower than true portrait focal lengths.

Can you use manual focus without switching modes?

Yes. The STM motor supports full-time manual override, so you can adjust focus on the fly during both stills and video without toggling any settings.

How close can this lens focus?

Minimum focus distance is 0.33 meters, with a maximum magnification of 0.13x - close enough for environmental detail shots but not a macro lens.

Is autofocus silent during video?

The STM stepper motor keeps noise low during video recording, though it's not completely silent like some newer designs.

What size filters does it take?

52mm filter thread, making it affordable to equip with ND, polarizer, or protection glass from major filter manufacturers.

Does the lens have weather sealing?

No. This lens has no weather sealing, so moisture and dust protection depends on your camera body and shooting environment.

How does the optical design handle chromatic aberration?

One ED element, one aspherical element, and two high-refractive elements work together to suppress chromatic aberration and field curvature across the frame.
