Sigma Sigma Art Sigma - 24-70MM F2.8 DG DN II ART Lens, Sony E Review

The Sigma 24-70mm f/2.8 DG DN II Art is a lens that leads with its optics. It lands in the 97th percentile for optical performance, which means you're getting some of the sharpest, cleanest images possible from a standard zoom. At 726g, it's not the lightest, but it's manageable for a constant f/2.8 zoom. The 82mm filter thread is common for this class, and the lack of stabilization is a notable omission you'll feel if your camera body doesn't have it built-in.

Let's talk about that 97th percentile optical score. That's the headline. In practical terms, this lens is razor sharp across the frame, even wide open at f/2.8. Chromatic aberration and distortion are minimal, which is a huge win for a zoom. The bokeh is smooth, sitting in the 71st percentile, so your out-of-focus areas look great. The autofocus, using Sigma's HLA system, is fast and quiet, though its 47th percentile ranking means it's competent but not class-leading. The 1:2.7 max magnification puts it in the 77th percentile for macro, so you can get decently close for a zoom.

At $1319, this lens is priced as a premium option. You're paying almost entirely for that 97th percentile optical performance. Compared to Sony's own GM version, you're saving a few hundred bucks for optics that are arguably just as good, but you're giving up weather sealing and possibly some autofocus performance. It's a value proposition for the pixel-peeper who prioritizes sheer image quality above all else.

This lens lives and dies by its optical score. The Sony 24-70mm f/2.8 GM II is its direct rival. The Sony is lighter, has better autofocus and stabilization, and is weather-sealed, but it costs more. The Sigma fights back with potentially better corner sharpness. Compared to primes like the Viltrox 35mm f/1.7, you lose over two stops of light and that beautiful shallow depth of field, but you gain the flexibility of a zoom. The Meike 55mm f/1.8 is another prime alternative; you'd get better low-light performance and bokeh, but you're stuck at one focal length. The Sigma is for the photographer who wants zoom convenience without compromising on sharpness.

If your primary goal is getting the sharpest possible images from a standard zoom, and you're okay with carrying the weight and forgoing weather sealing, the Sigma 24-70mm f/2.8 DG DN II Art is an easy recommendation. That 97th percentile optical score is no joke. But if you shoot in bad weather often, need the absolute best autofocus, or want a lighter kit, the Sony GM II or even a set of sharp primes might be a better fit. This lens is a specialist in a zoom's body.
