I've noticed that the mounting flange on both my DX lens are plastic. Is this true of all lens of this type? The 85 f1.8D lens is made of metal. Seems to me that may contribute to premature ware if changed often.

The heavier lenses still use metal but the lighter weight ones are plastic. Apart from lens snobbery I have never seen any reason to believe the the plastic is inferior or not as robust. Some of the metal mount lenses do have more weatherproof sealing than the plastic ones because they are designed for Pro usage.

I don't see lens snobbery having anything to do with it. The mounting flange on the camera is metal. Twist plastic against metal long enough and guess which one will wear down first? Plastic lens are ok I suppose but where it mounts to the camera should be metal. It couldn't cost much more to have a reinforcement there. The 16-85 VR I'm considering fortunately, does have a metal flange.
