To round up the 200/2 trivia exchanges: I originally had the 200/2 Ai, later changed to the latest AiS 'N' version so I could use [gel]filters. Later I acquired the first sample of the AFS 200/2 VR to arrive in my country. I have shot with the latest VR-II version, however any improvement over my current sample is not very significant and the trade-in costs excessive (I got my AFS 200/2 for a bargain price).
My 200/2 lenses both have very early 2xxx serials.
