Viltrox AF 56mm f/1.7 is now available for Sony cameras

Viltrox has a new Sony-fit version of budget-priced  AF 56mm f/1.7. Already on sale in NIkon Z and Fujifilm X mount, the lens is designed for use with APS-C cameras - and as such offers an effective focal length of 85mm – making it a great lens for portrait photography.

The ideal focal length for head-and-shoulder portraits, coupled with the wide f/1.7 aperture will enable the user to create shallow depth of field, isolating the subject from the background. With nine aperture blades, it promises the sort of dreamy bokeh that you usually only get with much more expensive prime lenses.

The 56mm f/1.7 has an internal focusing and a silent STM autofocus motor, enabling fast and accurate focusing for both stills and video. Vitrox says that the focus breathing is "almost imperceptible when the focus changes".

The lens is constructed from 11 elements in nine groups, including four extra-low dispersion lenses and three lenses with high refractive index, combating aberrations and dispersion. It weighs just 171g and is 72mm long.

Other features include HD multi-layer nano lens coating, a 52mm diameter filter thread, EXIF info transmission support, and a built-in USB-C port for updating firmware.

The AF 56mm f/1.7 sells for $180 / £139 / AU$315.
