Sigma 35mm f/1.2 DG DN Art Aperture Series: Mosaic (Sony A7R IV)

Sigma 35mm f/1.2 DG DN Art

This series evaluates the Sigma 35mm f/1.2 DG DN Art on an extremely demanding target: a planar subject with exceedingly fine detail. This target is among the most demanding any lens can face, mercilessly showing most all lens weaknesses.

Sony A7R IV 4-shot pixel shift was used to capture the best possible detail. Results with pixel shift will always look notably better than without (assuming no checkerboarding issues).

Field curvature is of particular interest because at 60MP, small deviations across the field are not so small, and stopping down past f/4 begins to degrade micro contrast from diffraction.

Sigma 35mm f/1.2 DG DN Art Aperture Series: Mosaic (Sony A7R IV)

Includes images up to full camera resolution of 60 megapixels.

This 2nd sample of the Sigma 35mm f/1.2 DG DN Art is not perfect, but it is much better than the first sample, and stunningly good when stopped down to f/5.6.
