Sigma 105mm f/1.4 DG HSM Art Aperture Series: Mt Conness Green Meadow, Dusk

Get Sigma 105mm f/1.4 DG HSM Art at B&H Photo. See also my Canon wish list and Nikon wish list and Zeiss lenses for DSLRs wish list.

This in-depth analysis evaluates far-field lens performance from f/1.4 through f/9 in mountain shade (dusk). Best possible wide-open performance is shown unequivocally since peak focus can be viewed where it cuts through the grass, thus also allowing an evaluation of field curvature.

Stopped-down performance from f/2 through f/9 provides insight into the peak resolving power capabilities of the Sigma 105mm f/1.4 DG HSM Art as well as how much real depth of field gains with stopping down. It also speaks to focus shift.

Includes images at sizes up to full camera resolution as well as crops, all from f/1.4 through f/9.

I like shooting the Sigma 105/1.4 a lot, but hiking with it is less pleasant!
