So I have an M3 and a Nikkor 50mm f1.4 LTM. I like the combination a lot but since I've only acquired this combination this summer, but I haven't had a chance to try any other lenses.... I've often thought about getting a 50mm f2.0 Summicron because that's the more "classic" combination, but is it noticeably "better"? Or offer a more distinctive look to make it worthwhile? I shoot at f2-f4 mostly as I feel that the DOF is just too shallow at f1.4, so I don't really need the speed per se.
