unimogbert -- Thanks, that's what I figured.

Hikermor -- Pan-X was the best I found available for we mere mortals. The photo guy in my first squadron used BW high contrast copy film and a tricked out Nikon F to get some amazingly high resolution prints. I couldn't do that with a standard Nikon FM and Pan-X, but he used that high contrast film and his own dark room (he had to finesse the developing process). Is there a useful conversion to compare digital megapixels with film ASA? Or is that an apples and oranges thing?
