Viltrox 85mm f/1.8 STM II Overview
Distinguished by its updated sleeker and lighter weight design, the Viltrox AF 85mm f/1.8 RF II is the second-generation of this portrait-length prime designed for Canon RF-mount mirrorless cameras. The lens’s short-telephoto focal length pairs with the bright f/1.8 design to suit working in a variety of lighting conditions and also for controlling depth of field and isolating subject matter. The optical design comprises one extra-low dispersion element, one aspherical element, and four elements made from highly transparent glass, which all help to reduce chromatic and spherical aberrations in order to realize high clarity and sharpness. An HD Nano multi-layer coating has also been applied to suppress flare and ghosting for improved contrast when working in strong lighting conditions. Additionally, the lens features an STM motor for quick, quiet autofocus performance along with a minimum focusing distance of 2.6′ for working with close-up subjects.
