Ok let's twist things up a little bit. I also have a 50mm f/2-H which is in very good overall condition, save for a small nick in the front element, which in the numerous rolls I've put through my F3 with it I've never noticed to degrade image quality.

Considering that my other two lenses are both AI, I'd be willing to do a trade for a nice copy of a 105 f/2.5 Ai or AiS for these two lenses. Only reason is because I intend to use these more for video work and I would like to have color consistency between all three lenses, where right now the 105 I currently have is a bit warmer in tone (which actually is quite pleasant).

Just a thought.
