Hi Mike

I can't say that what I know about digital rigs vs. film is true, but my sense is that the differences in the way the lenses work is in the adapters that are used to mount them. Basically I think you need to be careful to make sure that once the lens is mounted it still has whatever auto functions it had when mounted directly to the camera. Adapters tend to cut out any auto functions. Quite frankly, though, I'm not sure it is an issue for us in mineral photography. We tend to turn off any auto functions and take full control of the camera in manual mode - bring our own eye into the decision making loop as much as possible.

The main glitch I can think of might be that just finding an adapter to mate your old film lenses may be hard - or even possible - to do. No adapter being available, you are stuck with buying new lenses... As your friend notes that the digital lenses are more expensive than film lenses, I am cynical enough to suspect it is all a marketing ploy to get more of our dollars out of us when we make the switch.

Boo! Hiss! :~}
