Shootout: Sigma 24-35mm f/2 DG HSM Art vs 35mm f/1.4 Art: Cottonwood Canyon Cabin

Sigma 35/1.4 DG HSM Art

Get Sigma 24-35mm f/2 DG HSM Art and Sigma 35mm f/1.4 DG HSM Art at B&H Photo.

Can an optimized short-range zoom compete with a one-stop-faster prime lens?

Sigma’s 24-35mm f/2 DG HSM Art offers an excellent optional to address that question against its sibling, the Sigma 35mm f/1.4 DG HSM Art. If a zoom can deliver similar image quality, the 24-35mm range at f/2 may well be worth it for some shooters. But all zooms have compromises, and the Sigma 24-35mm f/2 has at least two notable comprises as are discussed here.

Sigma 24-35mm f/1.4 DG HSM Art vs Sigma 35/1.4A: Cottonwood Canyon Rancher’s Cabin

Entire-frame images up to 28 megapixels for apertures from f/1.4 - f/13. Multiple large crops and a focus stacked image at f/9 using the Sigma 35mm f/1.4 DG HSM Art also included, along with extensive analysis.

The results here are unusually useful—highly recommended reading for users using or contemplating either lens.

UPDATE: I also take a look at distortion and its impacts on sharpness when corrected:
