I've read thru the manual and i thought ETTL is supposed to be in effect with 420ex on even if its in M mode?
took a few pics in M mode and when i adjusted the exp to read +-0 and took the shoot, the flash overexposed the shot...had to set -2 flash exposure compensation to help save it but still abit overexposed. in other modes its all ok.
i actually brought the cam down to canon cust svc for them to have a look and they told me theres nothing wrong coz the internal flash is supposed to fire at full strength in M mode.. ok that i know but what about with 420ex on? dun have ettl also?hope its not a camera defect.
can some1 pls advise thanks.
