Picked these up the other day. So does anybody know, are Leica lenses supposed to be any good? Just kidding - I know about Leica. I don't know much, though - this is my first experience with their stuff. I probably won't be going very deep down the rabbit hole, but these old SLR lenses are not a bad way to dip a toe in the water. They certainly are quite a bit less expensive than the rangefinder glass. I'm sure looking forward to trying these bad boys out. Unfortunately, I'm going to have to wait for the adapter to arrive. Oh, well... if I can't practice with them at least I can practice ON them!
