Sigma 24-70mm f2.8 DG DN Art Review

The Sigma 24-70mm f2.8 DG DN Art is currently available on the Panasonic/Sigma and Leica L mount and the Sony E mount.  There is a good chance that we'll see this also on the Z and RF mounts in the future.  I really doubt that Sigma built the lens with only those two mounts capable of using the lens.  The Sigma 24-70 is meant to be your workhorse lens and of course, is cheaper than the OEM 24-70mm F2.8 lenses as well.

CameraLabs completed their review of the Sigma 24-70mm F2.8 DN Art.

Key features of the Sigma 24-70mm F2.8 DN Art.include;

• Aperture Range: f/2.8 to f/22
• Six FLD Elements, Two SLD Elements
• Three Aspherical Elements

Cons;

• Constant f2.8 focal ratio.
• Sharp and contrasty in the APS-C image circle.
• Good black levels in contra-light situations.
• Reliable AF operation
• Can swap mounts (at a cost) between Sony E and Leica L-mount.

Pros;

• Field curvature and softer performance at closer distances.

Conclusions;

With their third lens natively designed for full-frame mirrorless cameras and available in Sony E or Leica L-mount, Sigma is aiming at the enthusiast and professional who desires a large aperture 24-70mm lens as a workhorse without breaking the bank: The zoom range is fitting for a wide variety of photographic tasks from reportage to street photography, landscape and architecture. The large aperture helps gather enough light in challenging situations and give some background isolation to the subject. In my tests the Sigma 24-70mm f2.8 DG DN Art has proven that it is a well designed lens: It is sharp within the APS-C image-circle, has no longitudinal color aberrations, shows little veiling glare in contra-light situations, and has a pretty soft Bokeh plus reliable autofocus. And Sigma offers the unique option to get the lens-mount swapped.

What’s not to like? The Sigma becomes gradually softer at closer focus distances where it also develops quite some field curvature. This may not be relevant when shooting scenes with no important content outside the APS-C image circle. But it is a bit bothersome for a lens you’d want to use for many different types of scenes.
