All AF Nikkors have always had an aperture lock. And Nikon has great compatibility amongst most of their bodies. I can use all my current AF lenses on my 20 year old F3 with full function, and old AI lenses from the 70's work fine on my F100. Sure, they have some issues with their amateur line cameras, but the people that buy those are by and large not looking for complete compatibility with old stuff anyway. And Pentax has some issues with some of their cheapest AF bodies also. I think both Pentax and Nikon need to be commended on their compatibility between most bodies for older and newer items working together, especially comparing AF and non AF items. They are in a different league than Canon and Minolta in this regard.
