Viltrox Unveils the 85mm f/1.8 STM Lens for Nikon Z-Mount

Viltrox has quietly released its new 85mm f/1.8 STM autofocus prime lens for Nikon Z-mount mirrorless camera systems, making it the first third-party lens for the mount that features autofocus.

In fact, the Viltrox 85mm f/1.8 STM lens promises to support full autofocus on Nikon Z cameras, including eye-AF. It will work on all Nikon Z full-frame cameras, including the new Z6 II. The Z7 II is not specifically noted as supported, likely due to the fact the camera is not yet available.

This autofocus lens is constructed of 10 elements in 7 groups, including five short wavelength and high transparency elements and one low-dispersion element. Viltrox claims the lens, which uses a stepping motor (STM) to drive the autofocus elements, features full autofocus support, including compatibility with Nikon’s Eye-AF technology.

Other features include an aperture range of f/1.8–16, a nine-blade aperture diaphragm, an 80cm minimum focusing distance, and a 72mm front-filter thread.

Like the Sony and Fujifilm versions, the lens has a micro USB port in order to allow for firmware upgrades. Viltrox just announced updates for the Fujifilm mount, bringing improvements to the focusing speed.
