I have a nice Nikkor-O 50mm 2.8 which I want to trade for a Nikkor-H 50mm 3.5.
The reason is that I have another 2.8, and I that I want a 3.5 lens to replace one of them. I don't need two 50mm lenses of course, but this is only for fun to see how the two lenses compare.
The lens I want to trade has three small nicks on the front element, but they don't affect performance, and some marks from general use on the barrel. Othevise in very good condition.
