Sigma 28mm f/1.4 DG HSM Art Aperture Series: Alabama Hills, Dusk (Nikon D850)
See my Sigma SLR lenses wishlist at B&H Photo.
This medium range series evaluates lens performance from f/1.4 through f/5.6 at far distance.
Sigma 28mm f/1.4 DG HSM Art Aperture Series: Alabama Hills, Late Dusk
Includes images from f/1.4 through f/5.6 at up to full camera resolution.
I preferred the lighting and color balance of the images taken 20 minutes later, but this series is complete and better exposed so that noise is not an issue.
