This Sony SEL28F20 lens features a 9-blade circular aperture and ED glass with multicoating, so you can easily capture clear photos with minimal ghosting using your a7-series, 35mm full-frame camera.
Fast and light weight. 28mm is nicely wide on a FF camera in the A7 series. Also works with the cropped sensor models such as the A6000 (although it becomes a 42mm on those cameras).
