I am wondering if any of you have knowledge of, or experience in, using classic NAI Nikkors on the Canon 5D, a full frame digital SLR, or on any other AF optimized EOS Canon for that matter.
I have ten Nikkors I would like to use on a digital body. I understand that the new Nikon bodies will NOT support and meter through my old NAI glass. I have read that via adapters, EOS cameras will work and meter with those wonderful old Nikkors.
But I wonder about focusing. Most AF cameras' screens are optimized for AF and make manual focusing difficult. I wonder how difficult it is with the 5D. Any thoughts would be appreciated.

The Nikon D200 and D2 series cameras will all meter just fine with your old Nikkors in aperture priority and manual exposure modes. There is a menu provided so you can input the max aperture and focal length of your lens to assist with matrix metering.
To use those lenses on a Canon, you'd have to perform stop-down metering, which is ok for static subjects, but highly impractical for moving subjects (it becomes difficult to focus when you are stopped down as the viewfinder becomes dark) and for changing light conditions.
I did not realize that the d200 would meter with pre-AI, pronged Nikkors. That is very good news, if so. That it will also work with aperture priority auto is a boon too. I will have to look at d200 specs more closely.
I've never tried this (I don't even have a 5D to try it on) but I would say that if the metal prong doesn't get in the way that it should work. Since you're using an adapter (which one?) you should gain some extra room between the lens and where the prong might normally hit the underside of the EOS-5D's prism if it were mounted directly to the camera body (which of course is impossible to do).
Good luck and let us know how it works...I'm curious myself.
Pre-AI Nikon lenses should be used with extreme caution on (most) modern Nikon SLRs, it is advisable for them to be AI-modified as a pre-AI lens that hasn't been modified could damage the AI index tab on the camera body (or minimum aperture sensing tab on lesser bodies).
