The Viltrox Air 35mm F1.7 AF APS-C with Fujifilm X-mount – photographic lens with Fujifilm X mount is a compact and lightweight prime lens designed for mirrorless cameras with an APS-C sensor. Weighing only 170 g and measuring 64 × 54.7 mm, it offers a field angle equivalent to about 52.5 mm on full-frame format, making it ideal for portraits, street photography and reportage.

The lens is composed of 11 elements in 9 groups, including low dispersion (ED), high refractive (HR) and aspherical lenses, which reduce chromatic aberrations and distortions. Multilayer HD Nano coating enhances contrast and sharpness, minimizing flare and ghosting. A maximum aperture of f/1.7 allows for low-light work and pleasing bokeh thanks to the 9-blade diaphragm. Autofocus is handled by a silent and precise stepping motor (STM), which is compatible with the face and eye detection systems of Fujifilm cameras.
The minimum focusing distance is 33 cm, with a maximum magnification of 0.13x. The lens supports EXIF data transmission and firmware update via USB-C port.
