What is the viltrox af 15mm f 1 7 air good for?

The Viltrox AF 15mm f/1.7 Air is a wide prime for APS-C cameras. On those bodies it frames like a 22mm lens on full frame, which suits landscapes, street, interiors and group shots. The f/1.7 aperture helps in dim rooms and gives a little more background separation than you'd expect from a wide lens, about what f/2.5 gives on full frame. It has autofocus but no stabilisation, so keep the shutter speed up in low light.

It mounts on Sony E, Fujifilm X and Nikon Z. Good APS-C partners include the Fujifilm X-T30 III, the Sony a6700 and the Nikon Z50 II. It also works on full-frame Sony and Nikon bodies in APS-C crop mode, at fewer megapixels. For more on crop factors, see Sensor sizes.
