Lens Skew Study added to MSI
Added to Making Sharp Images is a new case study combining both pages of the recent lens skew study of the Sigma 35mm f/1.4 DG HSM A1.
Lens Skew (Nikon D800E, Sigma 35/1.4) under the Case Studies section.
This discussion applies to any brand lens on any camera. I have observed similar issues with Nikon, Canon, Zeiss, Leica M, Leica S, Olympus, Sigma— no brand exceptions.
