The AF 75mm f/1.2 XF Pro from Viltrox is the company’s latest autofocus lens for Fujifilm X-mount camera systems. The lens has a 115mm full-frame equivalent focal length and supports all of Fujifilm’s autofocus settings.

The AF 75mm f/1.2 XF Pro is made of aluminum alloy and employs 16 elements divided into 11 groups, four of which have a high refractive index and three of which have an extra-low dispersion (ED). Viltrox’s HD Nano multi-layer coating is also used on the front-most element to repel dirt and water.

The lens has a clicking aperture ring that can be adjusted manually or automatically, and it is weather-sealed in nine places for dust and water resistance. Other features include an f/1.2 to f/16 aperture range, an 11-blade diaphragm, a minimum focusing distance of 0.9m, and a 77mm front filter thread.

The lens’s autofocus is powered by Viltrox’s stepping motor (STM) mechanism, which the company claims supports all of Fujifilm’s eye-detection, face-detection, and animal-detection autofocus modes. The autofocus is driven by the metal electronic contacts, which also transfer EXIF data from the lens to the camera. The lens mount’s inbuilt USB-C connector is utilized to update firmware.
