The 35mm f/1.8 DT Alpha A-Mount Standard Prime Lens from Sony is designed for D-SLR cameras with DT-format, APS-C sized sensors, so the lens actually has the 35mm equivalent of a 52.5mm focal length. The ultra fast f/1.8 wide-open aperture, along with the 7-blade circular diaphragm, allows you to work in low light, and create very smooth "bokeh" out of focus background effects. With its minimum focus distance of 9.05" it also allows you to get in close to your subjects.
The internal Smooth Autofocus Motor (SAM) ensures responsive and fluid autofocus operation. The focus mode switch allows you to quickly switch between autofocus and manual, and the 55mm filter diameter allows the addition of creative filter effects onto your images.
