  1. I own three "L" lenses. They are ALL soft when mounted to an APS-C (small sensor) camera. BUT...they all three work VERY nicely, sharpness wise, when mounted to my full frame (larger sensor) 6D.

It is a given that the maximum 100% view pixel sharpness with the same lens and f-number will be higher with bigger pixels with the same relative AA filter strength. All lenses are very, very soft with small enough pixels, as it should be.

In this case, however, the OP's camera has a pixel size that is very close to that of the 6D. I have an APS-C camera that has pixels much larger than those in the 6D.
