Constant-aperture standard zoom for mirrorless

The Sony FE 24-70mm F2.8 GM II is a full-frame zoom lens with a constant F2.8 aperture across its 24-70mm range. It targets professional and enthusiast photographers and videographers who need a single versatile optic for events, portraits, landscapes and general reportage on Sony E-mount bodies.

Optical limits of the F2.8 constant-aperture design

The lens maintains F2.8 throughout the zoom range, fixing exposure while framing changes. Its floating focus mechanism and XA aspherical elements control aberrations at every focal length and aperture setting. The optical formula includes two ED and two Super ED elements to minimise chromatic aberration, while Nano AR Coating II suppresses flare and ghosting in high-contrast scenes.

Replaces the original GM model

This second-generation lens is 16 mm shorter and approximately 18 % smaller by volume than the previous version. Weight drops over 20 % to 695 g (24.6 oz), improving comfort during extended handheld shooting. The upgrade is worthwhile for users who carry the lens daily or work in tight spaces, while existing owners satisfied with size and AF speed may see less immediate benefit.

Questions about this item

Should I pick the 24-70mm F2.8 GM II or the earlier GM model?

The GM II is 16 mm shorter, about 18 % smaller by volume and over 20 % lighter at 695 g, while keeping the same constant F2.8 aperture and zoom range.

What does the constant F2.8 aperture actually give me when shooting?

It lets you hold the same bright exposure from 24 mm to 70 mm, so low-light shutter speeds stay fast and depth of field stays shallow for portraits throughout the zoom.

Is the E-mount on this lens limited to APS-C crop mode on full-frame bodies?

No — it is a native full-frame FE lens, so it covers the entire sensor on Sony Alpha mirrorless cameras without any crop factor.
