Sony E 20mm f/2.8 Overview
Wide-Angle Pancake Prime
Begin your wide-angle journey with the E 20mm f/2.8 Lens from Sony, a super compact "pancake" lens designed for APS-C-format E-mount cameras where it provides a 30mm equivalent focal length.
Compact Design
With its pancake design, the lens only extends 0.8" from the mount, resulting in a compact and lightweight camera system.
Portable design makes this a go-to lens for everyday carry and street shooting needs and the wide-angle field of view presents a natural perspective for a variety of shooting applications.
Bright f/2.8 maximum aperture suits working in available lighting and also contributes to the sleek size and lightweight design.
Optics and Focusing
Three aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
The lens uses a rear focusing design that contributes to faster autofocus performance as well as a minimum focus distance of 7.9".
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
