Designed for Sony’s full frame mirrorless camera line-up, the lens is also right at home on their APS-C range where it offers the equivalent of a 30mm focal length which makes it great for things like environmental portraits.

Bright Aperture f/1.8 and Separate Control Ring

Blessed with Beautiful Bokeh

A rounded 9-blade diaphragm paired with the wide f1.8 aperture delivers lovely and smooth bokeh effects in the out of focus background and highlight areas of your images. This look works really well for your close-up shots, helping make your subject really pop from the background.
