the Sony E PFU RBMH 85mm f/1.8 STM from Viltrox is also characterized by its bright f/1.8 maximum aperture, which excels in difficult lighting as well as benefits working with shallow depth of field techniques. The optical design comprises one extra-low dispersion element, along with four elements made from highly transparent glass, that aids in reducing 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.
