About this item

Written by Crutchfield's Woody Sherman

One of the best things a lens can be is portable. Weight and bulk can slow you down in a lot of ways, and while you can learn to get around those limitations (and should), it's always nice when you can say a quality lens weighs less than 3 ounces and is less than an inch long. Without further ado, we present the Sony SEL20F28 pancake-style lens for Sony E-mount mirrorless interchangeable-lens cameras.

You're no doubt already aware your Sony E-mount camera is a great example of highly compact digital imaging technology. With this lens mounted on the front, it becomes small enough to slip into a coat pocket, while still featuring a very useful 30mm equivalent focal-length and remarkable light-gathering ability thanks to its f/2.8 aperture. If you're willing to walk around a little bit to achieve your ideal framing, this lens will reward you with tack-sharp, light-suffused images that resonate down the years. The SEL20F28's candid snapshots, landscapes, and interior shots will all exude life, while its portability will keep you involved in the action around you.
