Sony E 20mm f/2.8 Overview

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. It offers shooters a fast f/2.8 aperture for use in low light and for creating images with a shallow depth of field. Benefitting image quality are three aspherical elements to minimize the appearance of aberrations while a rear focusing design improves autofocus speed and helps reach a minimum focus distance of 7.9". Additionally, the lens is equipped with a seven-blade circular diaphragm for smooth, rounded bokeh.

With its pancake design, the lens only extends 0.8" from the mount, resulting in a compact and lightweight camera system.
Optimized for APS-C-format cameras, this compact 20mm lens offers a wide-angle 30mm equivalent focal length.
The fast f/2.8 maximum aperture permits operation in less-than-ideal lighting situations and allows photographers to capture images with shallow depth of field.
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.

Sony E 20mm f/2.8 Reviews

Turn your a7iii into an iphone

This is a tiny lens with close to full frame coverage. Image quality is about on par with my iPhone 12 Pro 28mm camera, maybe a few stops faster, but not really sharper in dim indoor light on my a7iii. I'm glad I bought this to scratch that fujifilm x100 itch, but if you want to beat a phone, full frame with fast primes is the way to go.

Wonderful

Lightweight, small and optically excellent. This is a great wide angle walking around lens for Sony e mount aps-c cameras. It is outstanding on my a6500.

Terrific little lens!

It will make your Sony a6xxx even lighter and more portable - almost like a P&S - will fit into coat pocket. Sharper and faster than the kit lens, it is ideal for street photography and other wide applications. Even more desireable after the $50 price drop and with special free polarizing filter.

This lens on my a6000 is so small I can carry it in my coat pocket. I love the quirky lens shade in spite of all the complaints. It works and it is small.

Exactly what I expected

I got this lens to go on my Sony A6000 because it's a moderately wide pancake lens. I can drop this camera and lens combination with the Sony lens hood and lens cap in a cargo pocket in my shorts or pants and easily carry it with me. It comes out easily enough when I want to use it. The image quality is pretty much what I expected and is good enough for my usage. All-in-all, I'm pleased with the lens and find it to be just fine for this mode of use.

Quite the step up from the Sigma 30F/1.4

Image quality is about the same between Sigma's 30F/1.4 and this Sony. Where the Sony shines is in focus speed and all the electronics in it work as designed. This alone makes it a better choice. I do miss the 2/3RD of a stop though.

Nice little lens

fits my needs for just every day walk around stuff. definitely wanting something a little more wide open in aperture for the bokeh but definitely fits my needs at the moment!
