Smooth Trans Focus
STF stands for Smooth Trans Focus, which smooths the transition between in-focus and out-of-focus areas. The lens uses an apodization filter which improves bokeh. The lens features one nine-bladed and one ten-bladed aperture. They are both circular. The nine-bladed aperture, measured in f-stops, controls the depth of field, whereas the ten-bladed aperture, measured in t-stops, controls exposure.
Reception
The lens is rated highly by users. On Dyxum, a Sony lens database, the lens scores 4.86/5 from 36 reviews. The lens was tested by Photozone, who awarded it a highly recommended rating.
