Airy, thanks for that link! Together with Bjorn, Mir and Roland's pages it will serve me really well. I love finding pages like these!
I will be looking for an Ai version it seems, thanks to all for the prompt and insightful help.
Frank, while I would prefer slightly wider than 28mm I haven't found an alternative ~f/2 at a price I can afford currently. The f/1.4s and f/1.8s are pricier, bigger, and I really enjoy the feel of the manual Nikkors. If money was no barrier, I'd be giving the Zeiss 25mm f/2 a spin. Someday perhaps.
