Sigma 40mm f/1.4 DG HSM Art Aperture Series: Green Chairs at Sunset, Laws Railroad Museum (Nikon Z7)

See my Sigma DG HSM Art wishlist.

This far distance series evaluates lens performance from f/1.4 through f/11, evaluating sharpness across the frame as well as secondary color correction.

In diglloyd Advanced DSLR*:

Sigma 40mm f/1.4 DG HSM Art Aperture Series: Green Chairs at Sunset, Laws Railroad Museum

Include images up to full camera resolution from f/1.4 to f/11 as well as a 3-frame focus stack at f/11.

* 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.
