The Sony E 20mm F2.8 is a wide-angle prime lens for the Sony E-mount, announced by Sony in April 2013.[1]
The lens itself is made of a glossy black plastic shell over plastic internals and includes a detachable pancake-style lens hood. The lens itself is colloquially referred to as a pancake lens as it is currently the thinnest lens offered for Sony E-mount.
The lens can also be adapted with a 16mm ultra-wide angle or a 12mm fisheye converter, which are both sold separately from the lens itself. Neither allow for corrected Exif data to be recorded to the camera while the converter is attached.
