Sony FE 28mm F/2 SEL28F20

This Sony prime gives full-frame E-mount photographers a compact 28mm wide angle. It suits street photography, travel and interiors, where one fixed focal length keeps framing simple. The f/2 maximum aperture helps in dim rooms and evening streets. Sony introduced the lens in 2015, and it remains in production.

The main trade-off is the fixed focal length. You change framing by moving, which also changes the perspective between nearby and distant subjects. The lens suits photographers who prefer a small camera setup and can work around one wide view. Its light weight is useful when walking for long periods.

At 7.1 oz (200 g), this is a very light full-frame prime. The barrel measures 2.52 in (64 mm) across and 2.36 in (60 mm) long, so it adds little bulk to a body. The physical specification scores 64 out of 100.

A screw-in filter must match the 49mm thread on the front of the lens.

The 28mm focal length suits street corners, cramped interiors and layered travel scenes. You can place a nearby subject against a wider setting. Very close positions make the foreground look larger relative to the background. Keep faces away from the frame edges and avoid crowding a person when you want more natural proportions.

The f/2 maximum aperture gives you more light than a smaller opening at the same shutter speed. In dim rooms, you can use that light for a lower ISO or a faster exposure. Close subjects can have a blurred background even at 28mm. Greater subject distance and a smaller aperture keep more of the scene clear.

Manual focus reaches 0.8 ft (25 cm), measured from the sensor, with a maximum magnification of 0.16x. Autofocus has a slightly longer minimum distance and a lower maximum magnification. These close settings suit table details. The optics specification score is 82 out of 100.

There is no built-in stabilization. A camera with body stabilization can help with still subjects, while a steady hold or firm support offers other options. Wide framing is less sensitive to small hand movements than a long telephoto. Even so, use enough shutter speed for the subject and the light.

The design resists dust and moisture, which helps during outdoor use. Use cover in persistent rain. The front element lacks a fluorine coating, so water spots and fingerprints need ordinary careful cleaning. This does not mean the lens lacks other optical coatings. The features specification score is 32 out of 100.

The optical design uses nine elements in eight groups. Three are aspherical, including one advanced aspherical element. Their shaped surfaces help correct faults such as distortion and spherical aberration. This is useful when straight building edges run through the image.

Two ED elements help reduce coloured fringes along high-contrast edges. Internal focusing keeps the barrel length fixed as focus changes. The construction specification score is 54 out of 100.
