VILTROX 85mm F/1.8 F1.8 Mark II STM Full Frame 85mm f1.8 II for AF Auto Focus for Sony E-Mount Camera A7III A7RIII A7SII A7II a6500 a6400 a6300

A stepper motor (STM) is used to drive autofocus and the lens has a minimum focusing distance of 80 cm. The front filter size is 72mm and the integrated contacts operate the aperture mechanism and deliver EXIF data to compatible Sony cameras.

The lens, which has an aperture range from F1.8 to F16, is designed for full-frame Sony cameras, but also works as a 127.5mm equivalent on APS-C cameras.

It consists of ten elements in seven groups, including an extra little dispersion element and four special elements made of "highly transparent glass" that reduces aberrations and improves colour reproduction.

Uses an "HD Nano" multi-layer coating on individual elements to minimize ghosting and stray light.

The lens is a built-in micro USB port on the back of the lens. This connector is used to update the firmware of the lens.
