Andy writes: I am debating ... still debating ... doing the same thing that Karl suggests and that is to alter the front end of a digital camera (in my case the original digital rebel) by disabling the auto-everything connectors and installing an FD body flange ... As you know I already buggered up the back end of a couple of FD lenses so they fit on an EF or EOS body. But this in a way is too much work and easily subject to failure. OTOH I have now a VERY nice 135 f/2 Canon lens. Now got to use it more! uh-huh.. I know that feeling :) Even if I have to install a servo to maintain full diaphragm focussing and actuate the lenses on firing, I figure it'd be much nicer than mangling good FD mounts - especially as I still use film! .. and for me, as always, the lenses are more important than the camera =) - and there's only 2mm to dispose of!
