Sigma 24-70mm F2.8 DG DN II Art

The Sigma 24-70mm F2.8 DG DN II Art is a full-frame standard zoom released in 2024. It comes in Sony E and Leica L versions, so choose the version made for your camera.

The 24–70mm span suits varied subjects and everyday work. At 24mm it covers wide views of interiors and streets. At 70mm it narrows the view for portraits and tighter details. That flexibility makes this class of zoom popular for events and travel, where subjects and light keep changing.

There is no stabilisation inside the lens, so consider the camera body, shutter speed and support you will use. Weight is another factor when planning a kit for a long event or walking session.

The Sony E version weighs 1 lb 9.9 oz (735 g) and measures 3.46 in (87.8 mm) across and 4.81 in (122.2 mm) long. The L-mount version is heavier and shorter. Allow room for the hood and caps when packing. Screw-in filters must match the shared 82mm front thread.

The f/2.8 maximum aperture stays available at every focal length. At a given shutter speed, it can allow a lower ISO in dim interiors or evening streets. A close subject can have a soft background when there is enough space behind it. Available light still determines the settings needed.

At 24mm, closest focus is 0.6 ft (17 cm) and maximum magnification is about 0.37x. The minimum focus distance is longer at the telephoto end. Distances are measured from the sensor. Leave room ahead of the glass for light and avoid touching the subject with the lens.

A constant maximum aperture does not keep depth of field unchanged as you zoom. Focus distance and focal length also matter. Stop down when more depth is needed for a group, then check whether the resulting shutter speed suits the people in it.

From the same position, 70mm selects a smaller part of the scene than 24mm. Moving the camera changes perspective as well as framing. Check the relationship between near objects and the background after changing position.

There is no image stabilisation in the lens. A camera with body stabilisation can help with shake. Firm support helps during long exposures of still subjects, but a moving person or plant can continue to blur.

The body is designed to resist dust and moisture. Use cover in persistent rain and protect the open mount during lens changes. Dry the exterior before storage after a damp session.

The front element has a water- and oil-repellent coating to help with cleaning. Remove loose grit before wiping the glass. The zoom lock secures the barrel at the wide end for transport; release it before changing focal length.

The 19-element, 15-group design includes five aspherical elements. Their shaped surfaces help correct distortion and spherical aberration. Distortion can make straight building edges appear curved.

Both mount versions share six FLD and two SLD elements. These glass types help reduce coloured fringes along high-contrast edges. Internal focusing keeps barrel length unchanged as focus moves; zooming is a separate action. These features do not establish measured image quality.
