Lens Sony SEL28F20 — Sony E-mount 28mm f/2 prime lens

The Sony SEL28F20 is a compact 28mm f/2 prime lens for Sony E-mount cameras. Designed for use on both full-frame and APS-C mirrorless bodies, it provides a wide-angle field of view that is well suited to street photography, landscapes and environmental portraits. The bright f/2 maximum aperture supports low-light shooting and selective focus, while the physical design emphasises portability and compatibility with Sony E-mount autofocus systems.

Advantages

This 28mm f/2 prime lens offers a balance of optical performance and compactness: the wide-angle focal length captures broad scenes while maintaining subject separation thanks to the f/2 aperture. Autofocus is optimised for E-mount systems to provide reliable focusing performance, and the lens construction keeps weight and size low for easy carry and everyday use. The lens design provides consistent imaging behaviour on both full-frame and APS-C sensor formats.

Suitable for

• Street and documentary photography where a wide field of view and quick handling are needed
• Landscape and travel photography requiring compact optics
• Environmental portraits that benefit from contextual background and shallow depth of field
• Low-light situations such as indoor events and evening scenes

Key specifications

• Focal length: 28mm (equivalent field of view on APS-C bodies)
• Maximum aperture: f/2 for improved low-light performance and subject isolation
• Lens mount: Sony E-mount, compatible with full-frame and APS-C mirrorless cameras
• Optical design: prime lens optimized for wide-angle imaging
• Autofocus: designed for integrated E-mount autofocus systems
• Form factor: compact and lightweight construction for portability

How to use

Attach the lens to any Sony E-mount camera body until it locks into place. Use the f/2 aperture setting to achieve shallower depth of field and better performance in low light; stop down as needed for greater depth of field in landscape scenes. Focus can be set using the camera’s autofocus or manual focus controls where available. When shooting on APS-C bodies, expect a narrower effective field of view compared with full-frame sensors. Store the lens with caps on and use a protective bag or pouch to prevent dust and scratches.

Usage recommendations

For street and documentary work, use wider apertures and faster shutter speeds to freeze motion and separate subjects from backgrounds. For landscapes, stop down to mid-range apertures for increased sharpness across the frame. Use a lens hood or shade to reduce flare in backlit situations and clean the front element with a microfiber cloth to maintain image quality.
