The Sony 135mm f/2.8 STF Manual Focus A Mount Lens is equipped with Smooth Trans Focus technology which makes the defocused portions of your image look softer and more unique than your average lens. This affect can only be achieved with manual focus on this lens so it is not designed for fast-moving subjects. This lens is well suited for artistic still life photography and for portraits.
Notes: This lens is compatible with APS-C (crop frame) and full frame sensor Sony Alpha A Mount camera bodies. It is not compatible with NEX cameras or full frame E Mount cameras.
