I can understand it. Canon-ites like myself went through something similar about 15 or so years ago. It was annoying, but at least they did a total departure in mount from the old FD to new EF. That way you couldn't mount the old ones on new EOS bodies (at least, not without a special adapter ring). Back when I was looking at the D100, I tried to find all I could on what the different lens mounts where and what not. Could not find any kind of compatibility list anywhere on Nikon's site. You'd think they'd make that really easy to find. Will give it another looksee. -=>Donald
