Summary

The Viltrox AF 9mm F2.8 Air is a 9mm APS-C ultra-wide prime for Sony E, Nikon Z and Fujifilm X mounts, giving an approximate 13.5mm full-frame equivalent view, a constant F2.8 aperture, STM autofocus and a very light 175 g body in the Sony E version.

Its photographic value comes from the mix of a 113.8-degree angle of view, 0.13 m minimum focus, 58mm filter support and a 13-element, 11-group optical design with 2 aspherical, 3 ED and 3 HR elements. Recent reviews point to strong sharpness for the size, well controlled distortion and unusually good value for an autofocus 9mm lens.

It fits landscapes, architecture, interiors, travel, selfies, vlogging and close foreground perspectives with a lot of environment in the frame. The trade-offs are the demanding ultra-wide framing, simple physical controls and visible vignetting at F2.8 in even-toned scenes.
