One can make the “bad sample” argument. Accordingly, I obtained another copy of the Sigma 85mm f/1.4 DG HSM (brand new also), and pitted both against the Zeiss Milvus 85mm f/1.4 on a Zeiss Siemens chart at close range, to see if the results would echo the field shootout findings.
- Sample #1 of the Sigma 85/1.4 is the lens used for the November 2016 three-way shootouts and examples; it was brand-new out of the box for that work.
- Sample #2 of the Sigma 85/1.4 was brand new out of the box and never shot prior to this test.
- The Zeiss Milvus 85mm f/1.4 was about a year old, and has seen field use over that time.
One center crop from f/1.4 through f/4 for all three lenses makes a compelling confirmation.
