E 20mm f/2.8

The Sony E 20mm f/2.8 is a compact pancake prime lens designed for Sony E-mount APS-C cameras, delivering a 30mm equivalent focal length ideal for wide-angle and everyday photography. The lens extends only 0.8 inches from the mount and weighs just 2.43 ounces, making it highly portable for street shooting and travel applications. Its bright f/2.8 maximum aperture performs well in available light while contributing to the sleek, lightweight design.

The optical design incorporates three aspherical elements that reduce aberrations such as astigmatism, field curvature, and coma for improved image quality. The lens employs rear focusing for faster autofocus performance and achieves a minimum focus distance of 7.87 inches. A rounded seven-blade diaphragm produces pleasing bokeh when using selective focus techniques, and the 70-degree angle of view provides a natural perspective suitable for diverse shooting scenarios.
