What cameras fit the viltrox af 25mm f 1 7 air?
The Viltrox AF 25mm f/1.7 Air is a Sony E, Fujifilm X and Nikon Z lens, and the catalogue lists a long list of bodies it fits. I'd split them into two groups.
On the APS-C bodies it's a natural fit, framing like a 38mm lens on full frame. The Fujifilm X-T5 and Fujifilm X-T50 are good places to start if you want a compact, dial-driven camera with this lens. For Sony, the Sony a6700 is a strong all-rounder, and for Nikon the Nikon Z50 II is a sensible pick.
Full-frame bodies such as the Sony a7 IV and Nikon Z6 III also take it, but only in APS-C crop mode, which drops the resolution. If you own a full-frame body and want this lens for its light weight, that trade-off is fine. If you're buying a body for this lens, I'd go APS-C.
For the full picture, see the gear catalogue or the sensor sizes guide.
