Yeah, the 50L is definitely worth the money if you can afford it, I have no bad feelings about buying this lens, it's definitely the most used lens I have too, among quite a few nice ones. I still hope they release a new version soon that has a slightly different design. But, I must say, shooting with it on the 5D3 is far different (better) than shooting with it on the 5D2. But, I never had too many problems with the 5D2 either. It's a very dreamy lens, that the other Canon 50s cannot compare to really. It's sharp, plenty sharp enough at f/8, but you don't really buy this sort of f/1.2 lens to judge it at f/8, as it is, it's fine enough there. It's still the best at f/1.2 to f/2.2 or so. And that's like where I shoot with this lens about 99% of the time.
