Now I'm with you, Luis. This explanation makes more sense to me. I have no plans to buy the D800 right away if at all. But my son is at the top of the list at my local dealer so I'll have a better idea about lens compatibility early in the game. Over the years I have tried to get only the best lenses that Nikon offered. These lenses perform beautifully on the D3X. I have only seen 3 lenses that don't perform the way I like on my D3X. One has de-centered elements, one has been dropped and one just has poor resolution until f8 or so. I have an old 43-86 that I purchased in 1977 and haven't used in years. Maybe I'll see how that fares.
