I need a little advice here.
I have tried these combinations on both my 5d and the 40d, and both times, I get a ERR message after trying to take a shot.
My combinations are these...
(1) Life Size Converter + body/58mm reversing ring + reversed 28mm super-tak
(2) Sigma 1.4x + Extension tubes + body/58mm reversing ring + reversed super-tak
I am assuming that the camera won't create an exposure if it doesn't recognize a lens contact. The LSC and TC both have connection pins, and when I go reverseing using the body/ring, it thinks there isn't a lens?
