just recently i tried using a cheap flash (forgot the brand) for a day with my 300d. it worked fine, but when i got back, i noticed that my camera had a hard time auto focusing. usually half clicking would be fine, now i'd have to really press it hard. sometimes it wouldnt even work and it'll just shoot.
i've tried resetting the cam but it'll only work for a couple shots.
is it possible to re-install the firmware? will that work?
any advice? thanks!!!
