That Canon orphaned them without even a single digital body was a big betrayal of customers and a good reason to avoid Canon products. If and when I buy a dSLR it will probably be a Nikon, in part because Nikon has respected its promises and its customers. -- Best regards, John Buying a dSLR doesn't make you a photographer, it makes you a dSLR owner.

Fair enough, should have pointed that out explicitely. jue

Actually, you may find there's more of a mess with Nikon lenses than with Canon lenses. I have no problems using any Canon EF lens on any EF body. This isn't the case with Nilkon. Old Nikon lenses will physically mount on a modern Nikon body but will they support metering and all the exposure modes offered by that modern body? A friend has a Nikon D50 DSLR and an old Nikon telephoto zoom. The zoom works in one or two of the body's modes but not in all of them. Based on conversations over the phone, I think the two modes are Manual and Aperture priority. I read, when the EF mount came out, that the FD mount physically would not have permitted Canon to offer all the facilities they wanted on their autofocus lenses. Personally, I stayed with the FD bodies and lenses until there was something better on offer. Regards, Rog.
