Additional information:

The Sigma 24-70 mm f/ 2.8 EX DG Macro  is an all-purpose zoom lens for 35 mm and APS-C digital cameras of major brands. It is a good variant in price-quality relationship.

Equivalent focal length on APS-C cameras: 38 mm.

Constant aperture of f/2.8 throughout the entire range of zooming.

At f/2.8 the image is soft and not very sharp at all focal lengths. From f/4.0 and especially from f/5.6 onwards the lens is quite sharp.

9-blade aperture. Nevertheless, blurring of out of focus areas is somewhat coarse.

The optical scheme includes aspherical lenses and SLD elements. Principal aberrations are well corrected. Chromatic aberration occurs  only in very contrastive scenes.

The front lens of the Sigma AF 24-70 mm F2.8 EX DG MACRO does not rotate while focusing which enables the use of  petal hood, as well as polarized and gradient filters. Manual adjustment of sharpness is possible at any time by turning the focusing ring.

Due to the absence of a hyper sonic motor AF drive the focusing itself  is rather slow, with rather frequent focus hunting, especially in poor light conditions.

Color  rendering is natural, colors are not saturated. Contrast is average.

At wideangle sharpness is  good  in the center and on the edges. There is a slight drop in resolution on the edges.

Vignetting is pronounced at f/ 2.8 and a focal length of 70 mm.

Barrel distortion is visible at 24 mm.

Side and back light is not handled well, so a hood is strongly recommended.

The tag Macro in the lens designation is rather relative. Macrography is possible with a maximum magnifying ratio of 1:3.8 only.

The Sigma AF 24-70 mm F2.8 EX DG MACRO is fit  for all principal types of shooting especially on 35 mm sensors. It is limitedly fit for genre and  candid photography due to  mediocre functioning of the aperture at f/ 2.8  and rather slow autofocus.

Compatible hood: LH875-02,548

A soft carrying case and a petal hood are included with the lens.

Attention! Not all autofocus functions are available:

  • The lens version for the Pentax bayonet mount is not compatible with SF-series autofocus cameras.
  • The version for the Nikon bayonet mount is not compatible with D40, D40x, D60, D3000, D5000 cameras due to the absence of a built-in motor.

Built like a tank.


Not a good tank.

Can be used as a hammer.


Used this for 4 years and although I loved it, it just wasn't wide enough on an APSC body.

Never really found it that sharp either which was annoying, but a 10MP body always masked that a little bit. Frankly, the 18-55 Canon kit lens was better.

The other problem with mine was that at 60k it properly failed. The lens quickly developed a mechanical focus isse and the aperture mechanism started freezing/jamming more and more. 

Very disappointed in the end with this lens.

Good looks

Stable focusing accuracy

Good sharpness of the diaphragm 3.2



2.8 is too soft

Weight, without the use of the battery pack and wrist strap is difficult

Zoom ring a little, but the focus ring is too big. It is better to be the opposite.

Hood is not effective, it allows a side flare


In general, a good lens for its tasks. With proper sharpening can achieve interesting pictures on the open apertures. Used in the wedding photographies, an acceptable defect rate (with apertures 4.5-5.6, to open more at weddings was scary). Knowing the pros, cons and features of the lens, you still leave it for photography
