The Sigma is spec'd for full frame and works very well on FF with very similar caveats as the 50L on FF. Meaning very similar light falloff, softness towards frame edges, etc. But that said, it does work great on a crop.
The nice thing is that in practice, if you don't get hung up on the vendor, there are three good 50s to choose from with the Sigma sitting between the Canon 1.4 and 1.2L both in terms of price and "what it does". Consider the "asthetics" of the 1.4 and of the 1.2L as a range of sorts, and the Sigma sits between them about 2/3 of that range towards the 1.2L imo.
Toss the nifty 50 into the mix and we have four good 50s to choose from, all with a different optomization/price formulas. And as usual, a shot with the nifty by someone really capable and shooting a compelling subject is going to trump a shot with the 50L by a noob shooting his cat on the living room floor.![]()
I'd add a few more choices to consider: Zeiss and old FD/FL lenses with the Ed Mika adapter. Both would be manual focus.
