Sigma 24-70mm f/2.8 DG HSM Art Aperture Series @ 24mm: Alabama Hills Rainstorm Creek (Nikon D850)

See my Sigma SLR lenses wishlist at B&H Photo.

This near-to-far aperture series evaluates lens performance from f2.8 through f/11. It assesses lens symmetry and field curvature.

Sigma claims to MTF test its lenses as I understand it. How can a lens so obviously 'off' be shipped to customers?

Sigma 24-70mm f/2.8 DG HSM Art Aperture Series @ 40mm: Alabama Hills Creek Canyon

Includes images from f/2.8 through f/11 along at up to full camera resolution.

This creekbed is dry nearly every day of the year, but it had rained heavily all night long (an “atmospheric river” storm), a relatively rare event here. There was enough rain to cause road damage, indeed to cut hunks out in places and to turn some sections into creekbeds. The creek had no running water a day later.
