Sigma 135mm f/1.8 DG HSM Art Shootout vs Nikon 70-200/2.8 FL ED VR vs Zeiss 135/2 APO-Sonnar

Get Sigma DG HSM Art and see my recommended lenses for Nikon and recommended lenses for Canon.

See Sigma DG HSM Art lens reviews in diglloyd Advanced DSLR.

Close range shooting is often a weakness in many lenses designs, which intentionally or not “game” the lab testing system by not performing nearly as well at close range as at distance. There are issues such as sharpness and micro contrast, correction for secondary color, and breathing (change in focal length with focus distance).

In my review of the Sigma 135mm f/1.8 DG HSM Art in Advanced DSLR:

Sigma 135/1.8 DG HSM Art vs Nikon 70-200/2.8 FL ED VR (White Flowers, Nikon D810)

Includes images up to full resolution, with crops.

In Guide to Zeiss, I make it a 3-way shootout:

Zeiss 135/2 APO-Sonnar vs Sigma 135/1.8 DG HSM Art vs Nikon 70-200/2.8 FL ED VR (White Flowers, Nikon D810)

f2.8 @ 1/6 sec, ISO 64; 2017-05-10 14:29:48
