Sigma 14-24mm f/2.8 DG HSM Art Aperture Series @ 23mm: Sandy Wash in Side Canyon, Zion

Get Sigma 14-24mm f/2.8 DG HSM Art at B&H Photo.

Confirming conclusions about lens performance is best done by shooting numerous scenes and seeing that all is in accord. The less than satisfying performance seen in Across the Canyon View of Checkerboard Mesa at 22mm is here evaluated at 23mm in a more complex 3D scene, to rule out field curvature as an explanation for the disappointing results.

In my review of the Sigma 14-24mm f/2.8 DG HSM Art:

Sigma 14-24mm f/2.8 DG HSM Art Aperture Series @ 23mm: Sandy Wash in Side Canyon, Zion

Includes up to full resolution images from f/2.8 through f/11 plus a 3-frame focus stack at f/9.

It is important when testing a zoom to test it across the zoom range, and also with near focus and far focus. I am not nearly so happy with performance at 22mm as at 14mm.

This series and others are important to understanding how to get the best out of the Sigma 14-24mm f/2.8 DG HSM Art, just as my review coverage of the Sigma 12-24mm f/4 DG HSM Art was and is. A lens can be bought and used, but unless its behavior is understood, sub-optimal results are virtually guaranteed on 36/42/45/50 megapixels even with the best lenses. That is one goal I strive for in my reviews, which aim for practical working knowledge.
