Sigma 24-70mm F2.8 DG DN Art Sony E Mount 578965

Product Information

Now for focus-breathing with the lens at 24mm f16, manually focusing from infinity to the closest distance and back again.

In the case of Sigma, each lens comes with a 1-year warranty, with an extended 3-year warranty in the USA. Again with the Alpha 1 set to wide area with face and human eye detection, the tracking is effortless. As a newer lens, we expected the Sony to dominate in terms of image sharpness, and we have to admit it is more consistent across the image at wider apertures.Reproduction in whole or part in any form or medium without specific written permission is prohibited. Also, as far as AF goes between the 135's I've used both on the A9 and I couldn't tell the difference in AF speed. Zooming-in on the eyes reveals loads of fine details and again bonus points to the Alpha 1 and lens combo which delivered a 100% hit-rate in my portrait tests, here using a wide area and eye detection alone. But the full-frame mirrorless cameras from Sony, Nikon, and Panasonic provide built-in sensor-shift stabilization. The new mirrorless edition really ups the game, with no less than six top-grade FLD (‘Fluorite’ Low Dispersion) elements and two SLD elements.

The other lenses in this comparison are of similar weight except for the Tamron which is much lighter at 540g + 25g lens hood. The latter is a pity as the lens shows strong mustache-like distortions at the short end which are not easily corrected.As seen in the photos below, it complements a full-frame camera like the Sony Alpha A7 III that we tested it wit, although it feels somewhat out of place on a smaller APS-C body. I also tested whether Sigma’s newest zoom lens allows you to change the focal length without altering its focus. It's also a very quiet performer, which makes this lens equally well-suited to both video recording and more candid stills shooting. DG DN Art ships with a good quality soft case and also a plastic petal-shaped lens hood with a locking mechanism (LH878-03).
