I'm curious....I've never used a DSL of any kind so, please forgive me if this is a dumb question but, I would have expected the AI-S Nikkors to play nice with the pro level (and advanced amateur) Nikon FX DSLRs.
What is the nature of the incompatibility?
I would have suggested the very best 28mm manual focus lens ever made (the 28mm F/2.8 or f/2.0 AI-S Nikkor) but it seems like that would be any better in the 'play nice' category that wht you have...
So, why don't they play nice?
EDIT: incidentally, I don't think Nikon has ever made a bad 28mm prime lens.They're ALL excellent. Many are/were the best you could get at the time.
