i have a canon 50D and 70-200mm F4 L USM lens
i have couple newbie questions
when i take pictures in low-light condition , the small screen ( pathviewer or something ) got a busy signal , my flash keep flashing very fast and i cannot take photos also , this happen when i use AF ..and also the F4 on the spec display screen also blinking
This wont happen again when i change to MF but i still prefer to AF but cant take photos with that condition...
Thanks in advance
