135mm f/2.8 STF Lens

Exceptionally smooth bokeh with sharp subject matter are the calling cards of the 135mm f/2.8 STF Lens from Sony. Equipped with Smooth Trans Focus technology, this lens uses apodization optics in order to diffuse the edges of out-of-focus elements, rendering them even smoother than a standard lens can produce. The f/2.8 maximum aperture assists in capture images with shallow depth of field, though with the apodization elements this functions as a T4.5. The lens also features a manual focus design with a manual focus distance of 2.9'. Additionally, it features both a ten-blade manual aperture diaphragm and a nine-blade auto aperture diaphragm, both rounded to create smooth bokeh.
