Sony FE 24-105mm F/4 G OSS SEL24105G

This Sony E zoom covers 24–105mm on full-frame cameras. The range suits travel, events and everyday photography that moves between broad scenes and individual people. You can change framing without changing lenses when the scene develops quickly.

Sony introduced it in 2017. Its f/4 maximum aperture stays available throughout the zoom. The main trade-off is light gathering. For frequent moving subjects in dim rooms, a wider maximum aperture can give more room for a fast shutter speed or lower ISO.

The lens weighs 1 lb 7.4 oz (663 g) and measures 4.46 in (113.3 mm) long and 3.28 in (83.4 mm) across. Consider the camera and lens together when choosing a bag or strap. Screw-in filters must match the 77mm front thread to attach directly.

At 24mm, you can show a room, street or person with more surroundings. At 105mm, a distant detail becomes larger from the same position. How much of the frame it fills still depends on distance. A wider lens may help when a small room limits where you can stand.

The maximum aperture remains f/4 as you zoom. You can retain that opening when framing changes, though a different part of the scene may need a different exposure. Sunlight and shade can need different settings even when the aperture stays unchanged.

A nearby portrait subject can have a soft background at f/4 when there is enough space behind them. Objects directly behind the person may remain distracting. Change viewpoint when the location allows, and stop down when people at different distances must stay sharp.

Closest focus is 1.2 ft (38 cm), measured from the sensor. Maximum magnification reaches 0.31x, useful for larger details such as flowers, food and carefully arranged table settings. Leave room ahead of the front glass when working close.

Optical SteadyShot reduces camera shake when you work handheld. A still scene can allow a slower shutter speed than a moving person. Stabilization does not stop subject movement, so walking guests still need enough shutter speed. Firm support remains useful for long exposures.

Dust and moisture resistance help outdoors. Use cover in persistent rain. Fluorine coating helps water and oily marks wipe away from the front glass. Remove loose grit before wiping spots, especially after working near sand or soil.

The rotary zoom ring changes framing manually. There is no zoom lock switch. Keep the lens supported when carrying the camera between locations.

Four aspherical elements include two AA elements. Their shaped surfaces help correct distortion and spherical aberration, which can bend straight lines or soften detail. Three ED elements help reduce coloured fringes along high-contrast edges, such as a roof against bright sky. These elements address different optical problems. Their presence alone does not show how much detail the finished lens records, or how it compares with another zoom.
