Sony E 16mm F/2.8 SEL16F28

Sony's E 16mm F/2.8 is a fixed wide-angle prime for Sony E APS-C cameras. The 16mm focal length suits interiors, architecture, street scenes and landscapes. It can take in rooms and buildings from close by, though framing still depends on where you stand and how large the subject is.

Released in 2010, this is an older design with a short feature list. There is no built-in stabilisation or weather sealing. Its small body appeals to photographers who want to keep their equipment compact.

It suits travel and everyday photography when a wide view matters more than zoom flexibility. Check the focal lengths you already own before adding it as a second lens. A fixed 16mm view changes framing through camera position.

The lens weighs 2.4 oz (67 g) and measures 0.89 in (22.5 mm) long and 2.44 in (62 mm) across. This pancake shape adds little bulk to the camera. A screw-in filter attached directly must match the 49mm front thread. Consider the camera and lens together when checking space in a small bag.

On an APS-C sensor, 16mm gives a very wide frame. That helps in rooms, narrow streets and building interiors where you cannot move back. Landscapes and architecture also suit it, since near and far elements can share one picture. Framing still depends on subject size and distance, and perspective follows viewpoint rather than focal length.

The f/2.8 maximum aperture gives more room for a faster shutter speed or lower ISO than a smaller opening. This helps with dim interiors and evening streets. The available light and subject movement still determine suitable exposure settings.

Closest focus is 0.8 ft (24 cm), measured from the sensor. A nearby plant, door handle or paving stone can become prominent against the scene behind it. Leave room ahead of the front glass and check that the camera does not cast a shadow over the subject.

Depth of field depends on focus distance and aperture. A wide view does not guarantee that everything is sharp. Stop down when detail at several distances matters, and check nearby foreground objects as well as the main subject.

There is no stabilisation in the lens. A camera with body stabilisation can help reduce shake for still scenes. Firm support helps with slower exposures in dim interiors. Moving people need enough shutter speed for their movement too.

There is no weather sealing, so shield the lens from dust and heavy moisture. The front element also has no fluorine coating, so cleaning needs ordinary care. The features specification scores 19 out of 100.

The five-element, five-group design includes aspherical glass. Its shaped surfaces help correct optical faults such as distortion, which bends straight lines. This matters when walls and doorframes fill a wide scene. Internal focusing keeps barrel length unchanged as focus moves.
