The E 20mm F2.8 is built around keeping a Sony APS-C camera easy to carry. At 69 grams and about 20.4 millimeters long, it adds little bulk to a body that might otherwise be left at home. Its 30mm-equivalent view includes context for travel, street scenes and casual indoor photography. The fixed focal length encourages you to choose your position rather than relying on a zoom ring, and the 0.2-meter minimum focusing distance gives some flexibility for nearby details. Choose it when a slim walking setup is the priority. The F2.8 aperture is useful, but photographers concentrating on very dim venues or strong background separation may prefer a larger, brighter prime.
