85mm - 135mm

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.
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 reduces aberrations and improves color rendering.
