The Sigma 50mm F1.4\'s MTF drops off a cliff after a 15mm circle (about coveres a Canon APS H-1.275x sensor). Not such a good lens for FF.
The EF 85L does the same thing:
Black and grey lines show wide open performance.
The Sigma again, just for comparison:
Judging only by the MTFs (which only hold so much water) I\'d say the Sigma will be a terrific lens on FF.
