The Sigma lens delivers outstanding image quality. Its workmanship is excellent, the features very good.
An optical image stabiliser is missing. The lens is dependent on the solutions of the cameras to counteract shake, which is rare with wide-angle focal lengths.
The new Sigma lens is comparable in price to the Sony FE 24mm f/2.8 G, but offers a full aperture stop faster and is equal in image quality and AF performance. This makes the Sigma 24mm F2 DG DN | Contemporary the better alternative.
