Sony E 20mm f/2.8 Lens

A compact and lightweight lens, the E 20mm f/2.8 offers a 30mm equivalent focal length on Sony’s APS-C-format cameras. Adding only 0.8" to the length of your camera, it is perfect for on-the-go photographers looking for an easily pocketable lens to pair with Sony’s small form factor cameras. Three aspherical elements are incorporated into its optical design to reduce aberrations, and a rear focusing design boosts autofocus speed. A relatively fast f/2.8 aperture handles low-light scenarios with ease while a seven-blade circular aperture produces smooth bokeh in out-of-focus areas.
