Sigma 40mm f/1.4 DG HSM Art Aperture Series: Painted Rock (Nikon D850)

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.

In diglloyd Advanced DSLR:

Sigma 40mm f/1.4 DG HSM Art Aperture Series: Painted Rock

Include images up to full camera resolution.

I have mixed feelings about the Sigma 40mm f/1.4 DG HSM Art; it is capable of outstanding results and yet the focus shift makes it a chore to work with.
