Chinese camera accessory manufacturer Viltrox has announced a new 85mm F1. 8 autofocus lens for Sony E-mount camera systems. The lens, which has an aperture range of F1. 8 to F16, is designed for full-frame Sony cameras, but also works as a 127.
5mm equivalent on APS-C cameras. It's constructed of ten elements in seven groups, including one extra-low dispersion element and four specialty elements made from 'highly transparent glass,' which Viltrox says reduces aberrations and improves color rendering. Viltrox also uses an 'HD Nano' multi-layer coating on individual elements to minimize ghosting and flares.
A stepping motor (STM) is used to drive the autofocus and the lens features a minimum focusing distance of 80cm (2. 62ft). The front filter size is 72mm and integrated contacts power the aperture mechanism and deliver EXIF data to compatible Sony cameras.
Viltrox doesn't provide the dimensions of the lens, but it weighs 636g (1. 4lbs). One of the more interesting elements of the lens is an integrated microUSB port located on the rear metal mount of the lens. This connector is used to upgrade the lens' firmware, which is currently listed as version 1. 01 at launch.
B&H currently has the Viltrox 85mm F1. 8 STM Lens for Sony E-mount available to pre-order for $379. The expected shipping date is May 6, 2019.
