I've got a Nikon 65mm f4 which is just a little short for me... and I want to consolidate my 65 and 90 into one lens. So I'm hoping to get my hands on a fast 75mm from any of the big 4.

If that can't be managed, I understand the Schneider 75/8 has a 49mm filter which plays nice with my other lenses, so I'm open to that option too if someone has a multicoated one.

About my lens - it's not perfect as it's got a little scratch in the rear cell. Otherwise the coatings and everything are really nice - front cell is mint. I'm not terribly picky about my gear so it works fine for me, and I'm happy to accept a similar condition lens in trade.
