Re: Canon 350D for photomicrography?

Does the EOS Rebel XT (350D) meter on a T-mount (without CPU lens). I am
also interested to know if the TTL flash control still works when the camera
body is attached to a T-mount.

BTW, just using a regular eyepiece is fine as long as you move it out a
little. But why don't you just project the real image onto the CMOS image
sensor? With 8MPixels you can afford some vignetting that you just crop away
in SW ending up with a 6MPixel image at 12-bit sampling (if you shoot in
RAW).

Thanks,

Gregor
