Sony 135mm F/2.8 STF Alpha Mount Autofocus Lens {72} Description


Sony 135mm f/2.8 SFT telephoto lens allows you to create true unique images with stunning smooth transitions between in-focus and defocused areas. Smooth Transmission Focusing (STF) system delivers a pleasing effect via the apodization lens element that smooths out-of-focus areas. Objects stand out against smooth, even backgrounds. A manual aperture ring and circular aperture give you added control over defocusing, which is especially desirable around T4.5 to T6.7.

A unique telephoto lens for smooth, natural focus effects in foreground and background. This advanced STF (Smooth Transition Focus) telephoto lens incorporates an apodization optical element that distributes light rays to create smooth, aesthetically pleasing out-of-focus backgrounds that make sharp-focus subjects stand out more vividly. Mounted on the Sony alpha DSLR-A100 camera, this lens provides a 200mm focal length (35mm equivalent).
