Sony E 20mm F2.8 (SEL20F28)

A Compact Wide-Angle Prime
The Sony E 20mm F2.8 is an APS-C prime lens for Sony E-mount cameras. It gives a 30mm-equivalent field of view on APS-C bodies, making it useful for landscapes, interiors, street scenes, and everyday shooting.

Built for Portability
This lens is very slim and lightweight, with a pancake-style design that makes it easy to carry. It has a 20.4 mm length and weighs about 69 g, so it is one of Sony’s most compact primes.

Practical Optical Design
Sony uses three aspherical elements to help control distortion and improve contrast across the frame. The rear-focusing design keeps the barrel from extending during focusing, which helps with handling and allows closer focus.
