This light, low-profile F2.8 wide angle lens is perfect for everyday shooting. Its minimised weight and bulk makes it easy to carry in a coat pocket or bag. It looks stylish too in a high quality alloy barrel finish. The high-performance optics with an aspheric surface provide excellent contrast and sharpness. The smooth, quiet, high-speed autofocus and aperture adjustment is ideal for still and HD movie shooting. And the 7-blade circular aperture is great for beautiful defocus effects. Designed for use with Sony NEX series.
