Sigma 40mm f/1.4 DG HSM Art Aperture Series: Mining Gears (Nikon Z7)
See my Sigma DG HSM Art wishlist.
This medium range series evaluates lens performance from f/1.4 through f/11 paying special attention to focus shift, which is extremely troublesome in this series, to the tune of 3 stops.
Sigma 40mm f/1.4 DG HSM Art Aperture Series: Mining Gears
Include images up to full camera resolution from f/1.4 to f/11, along with crops.
* The Sigma 40mm f/1.4 DG HSM Art is a DLSR lens, but I shot it on the Nikon Z7 with the Nikon FTZ lens adapter a lot to avoid dealing with focusing errors and to more easily deal with focus shift.
