I'm using this flash to cover for all my event shoots, no problem. Guess I just have a really gd copy. So it's not all lost cost for people who are looking at purchasing 540.
i got my flash and asked bout the 20D
was told they'll try to order if there're at least 5 people interested
3 people have already put their names down so i added mine
they said they'll try to get a better price if more people interested
My AF-540 so far also no problem... only problem is i dunno how to make full use of it... still learning and understanding PTTL flash... probably need to shoot more using the flash...
My old N flash SB-xxx also used to have problems...after a while u learn to live with it and overcome them
