Leica 18mm f/3.8 Super-Elmar-M ASPH Aperture Series: Mosaic (Panasonic S1R)

See my L-mount mirrorless wishlist and Leica M wishlist.

With each new mirrorless camera system, hope springs eternal even as basic physical facts are ignored (sensor cover glass). No, micro lenss do not fix sensor cover glass issues. Leica M lens performance is always impaired by ray angle when the sensor cover glass of a mirrorless camera has differing (greater) thickness than the optical path designed for the lens. The negative effects increase with distance from optical center and can include sharpness losses and amplification of field curvature and astigmatism.

This page evaluates performance of the Leica 18mm f/3.8 Super-Elmar-M ASPH on the 47-megaixel Panasonic S1R from f/3.8 through f/11. We should expect poor performance at f/3.8, but what about f/8 and f/11?
