Get Sigma 14-24mm f/2.8 DG HSM Art at B&H Photo.
Published in my review of the Sigma 14-24mm f/2.8 DG HSM Art is a look at performance at 14mm:
Includes full resolution images from f/2.8 through f/13, plus a 4-frame focus stack at f/8 along with commentary on depth of field challenges and lens performance. Series presented in color, but also with a full resolution black and white rendition of the focus-stacked image.
If you’re a landscape photographer and are looking for a zoom in this range, I recommend nabbing the about $1299 Sigma 14-24mm f/2.8 DG HSM Art. It offers tremendous performance at a very low price (relatively speaking). It makes a terrific 14mm prime lens, with a bonus feature of zooming to 24mm!
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.
