I'm sure it would be easier to only look forward and not look back. But I've remained a loyal Nikon user because over the years they've remained true to the F mount.

It was one of the few AF cameras that could use the older AI-S lenses with the new matrix meter because, as I understand it, it had mechanical coupling for the older lenses in addition to the electronic contacts for the newer lenses. I could be wrong. Of course, I believe the mechanical coupling was ultimately dropped because of cost in later models. Frank Farmer Jackson, Miss.
