Viltrox X 35mm f/1.7 STM

The Viltrox AF 35mm f/1.7 Air is a nimble, value‑focused standard prime for APS‑C mirrorless cameras. With a bright f/1.7 maximum aperture it offers good low‑light performance and pleasing subject separation while remaining extremely compact and lightweight — typically around 170g — making it ideal as a walkaround optic for street and travel photographers. Its optical design uses 11 elements in 9 groups, including aspherical and extra‑low dispersion elements and two high refractive index elements, producing strong sharpness across the frame and well‑controlled chromatic aberration. The lens lacks an aperture ring and weather‑sealing, but the build quality is solid with a metal mounting plate and a USB‑C port for firmware updates. Autofocus is driven by a stepping motor that proves fast and quiet for stills and smooth enough for video. A 52mm filter thread, inclusive petal hood and supplied pouch add convenience. Overall, the Viltrox 35mm f/1.7 delivers exceptional optical value for photographers seeking a compact, fast prime for everyday use on Fujifilm X, Nikon Z DX and Sony E APS‑C cameras.
