Sony FE 28-70mm F2 GM

This Sony E zoom covers 28–70mm on full-frame cameras. Sony introduced it in 2024. Its constant f/2 maximum aperture is useful for weddings, events and portraits in dim light. The range lets you change framing as people and scenes move.

The main trade-offs are weight and width. The zoom starts at 28mm, so a wider lens can include more of a small room from the same position. Plan how you will carry the full camera setup during long sessions.

At the long end, you can give one person or a table detail more of the frame. A longer lens adds reach for distant subjects.

The lens weighs 2 lb 0.4 oz (918 g) and measures 5.5 in (139.8 mm) long and 3.66 in (92.9 mm) across. A rest can take the weight during pauses between photographs. Screw-in filters must match the 86mm front thread to attach directly.

The maximum aperture remains f/2 throughout the zoom. You can retain that opening when framing changes, though a different part of the scene may need a different exposure. In a dim venue, f/2 gives more room for a faster shutter speed or lower ISO than a smaller opening.

At close portrait distances, f/2 can give a thin zone of sharp focus. A background far behind the person can become soft. Focus on the eye that matters most, then stop down when more of the face or another person must stay sharp.

At 28mm, you can show people with some surroundings. At 70mm, one person becomes larger from the same position. How much of a group fits still depends on where you stand. A change of viewpoint may improve the background more than a zoom adjustment.

Closest focus is 1.2 ft (38 cm) throughout the zoom, measured from the sensor. Maximum magnification reaches 0.23x, useful for bouquets and place settings. Very small objects remain modest in the frame. Leave room ahead of the glass and avoid shading a nearby detail.

There is no stabilization in the lens. A camera with body stabilization can reduce shake for still scenes. Firm support helps with slow exposures and controlled video work. A moving person still needs enough shutter speed for their movement, regardless of camera stabilization.

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 cleaning, 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.

Six aspherical elements include three XA elements. Their shaped surfaces help correct distortion and spherical aberration, which can bend straight lines or soften detail.

One ED element and three Super ED elements help reduce coloured fringes along high-contrast edges, such as a white dress against a dark doorway.
