Even though both the Panasonic S1R and the Leica SL2 are L-Mount cameras, they differ in their sensor cover glass thickness, which because of ray angle interactions, damages performance for M-Mount lenses and damages performance for Leica SL lenses.

The Sigma 28mm f/1.4 DG HSM Art for L-Mount cannot be optimized for two different sensor cover glass thicknesses, so on which camera does it perform better?
