Viltrox’s AF 9mm f/2.8 Air Lens For X-Mount

credits: Viltrox

Viltrox has released a new ultra-wide option for Fujifilm shooters, the AF 9mm f/2.8 Air. It is an autofocus APS-C prime that lands at a 13.5mm full-frame equivalent and covers a 113.8° field of view. Inside, Viltrox is using a 13-element, 11-group optical layout that includes two aspherical elements, three extra-low dispersion elements, and three high-refractive elements to help keep distortion, chromatic aberration, and edge softness under control despite the angle.

The lens measures 65 × 56.7 mm and weighs only about 175 grams, so it is lightweight enough for everyday carry or for mounting on smaller Fujifilm bodies without throwing off the balance (it is part of the lightweight series after all). Despite the compact build, it keeps a reasonably fast f/2.8 aperture and a standard 58mm filter thread, something not always guaranteed on ultra-wide primes. The minimum focusing distance is 0.13 meters, which allows for some exaggerated foreground-and-background separation and magnification tops out at 0.15×.

Autofocus is driven by a quiet internal motor and supports full eye- and face-detection AF on Fujifilm bodies. The lens uses a metal mount and includes basic sealing against dust and light moisture. There is also a USB-C port built into the rear cap for firmware updates. The Viltrox AF 9mm f/2.8 Air is available for 199 USD / 229 EUR.
