New 20mm f/2.8 E-mount Lens for Sony NEX Cameras.

Here is the new E-mount lens from Sony. The 20mm f/2.8 pancake lens, part number SEL20F28, from Sony is a native E-mount lens which means full compatibility, autofocus and auto-aperture, with all the NEX cameras. The 20mm pancake is 20mm in depth, the 16mm pancake is 22.5mm in depth. This means a slightly more compact package on NEX bodies, see the NEX-5R with 16mm below. The lens will provide an equivalent fov of 30mm when used on the APS-C sensor.

The SEL20F28 20mm pancake lens will sell for $350 and will be available in April of this year. It makes the $250 16mm pancake seem like a bargain.
