Use of Angle Finder with long Telephoto Lens
Does anyone have experience of using an Angle Finder on a digital SLR fitted with a long Telephoto/Zoom lens? I have a Canon EOS 350D (EOS Digital Rebel XT) plus a Sigma 50-500mm APO EX DG HSM lens. I would hope the extra variable magnification of the Canon C Angle finder would assist focusing, but was wondering if the image in the Angle Finder would be very dull used with this set-up, due to the many pieces of glass involved?
