When I shot this scene, I did so partly to check for focus shift, which proved prescient. The field curvature and focus shift behaviors of the Nikon 24-70; must be understood for optimal results.

This series looks at a quite pronounced focus shift of the Nikon NIKKOR Z 24-70mm f/2.8 S at 31mm from f/2.8 through f/11. It confirms the findings of a moderately strong focus shift also seen in Natural Bonsai over Beaver Pond and details how much shift and how to compensate for it.

Includes images up to full camera resolution from f/2.8 through f/11, plus crops. I would have shown a stacked image, but for the first time, the Nikon Z7 “focus stack” features failed, generating incompatible images—dunno what happened.
