Overview

The Sony 135mm F2.8 (T4.5) STF is a specialized manual-focus lens prized for its apodization element, which delivers exceptionally smooth bokeh. Optically, it is very sharp with negligible distortion and well-controlled chromatic aberrations, though purple fringing can occur in high-contrast scenes. Build quality is top-notch, but the manual focus can be challenging even with peaking. It suits portrait and landscape photographers who prioritize bokeh quality over autofocus speed.
