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.

Perfect One-Lens Solution
By Marcelo
Rated 5 out of 5
Date: 2026-06-22
This is a great lens for travel, walk-about or street if one is looking for an ultra-light single lens solution. The lens is super lightweight, decently sharp and features a perfect (for me) focal length for general photography (I don't do video). Auto focus is accurate, however it's great just to set it to f8 and 3m focus distance and just snap pictures since everything from 1.5m to infinity will be reasonably sharp. I can't even tell I have a lens when it is attached to my A6700. If packing light is your priority nothing beats this lens.

Tiny lens that delivers. Took it as the only lens for our park days at Disney and it did fantastic.

How does this compare to the 16-50mm f3.5-5.6 kit lens? Is it worth getting if I've already got the kit lens?
Asked by: Troy
This is probably one of the best lenses you can get for e-mount. And it's cheap. If you're a very good photographer, you might be able to get away with using the kit lens and still pull good shots. I'm a novice and I shot noticeably better images with this lens. The main draw for me was the size. It's half the height of the kit lens from the camera body, and I can fit my 5100 in my pocket very easily. At first I thought this would be a wide angle lens, then I realized it's 33mm in full frame equivalent. So think of this as a very portable, clear shooting 35mm prime.

question
Will this be an actual 20mm on a Sony A7R?
Asked by: Anonymous
This lens is also not designed for 35mm sensors. Lenses for 35mm work on APS-C but not the other way around.

Does it allow full manual control of the focus?
Does it allow full manual control of the focus?
Asked by: Gerardo
If the camera is set to manual focus, then you would be able to use the focus ring on the front of the Sony E 20mm f/2.8 Lens to focus the lens manually. The lens does not have a built-in aperture ring, so you would have to set the aperture of the lens using the control dials on your camera body.
