Just received my Cleon 8 and am very impressed with the look, feel and quality of the pieces. However I only tried it once on my 50D, while shooting a sunrise on a bitter cold morning. It goes through the focus and shoot OK, but when the button is half pressed for focussing the metering indicator lights all over the place can't seem to settle and lock on anything.
Before I try it again, I'd like to canvass other users of this combination to see if anyone ele is having this issue on the 50D. Could it be the environment (temperature), my subject, my technique or possibly a defective unit?
