problem with eos 1d and flash 550 ex

[sgiansakidis]

i have a problem with my eos 1d and 550 ex flash.the most pictures are underexposed but the main problem is that all pictures in the same place the same light contitions with the same shutter speed 1/60 and the same aperture 5,6 are different.also the camera works fine with indepentent flash in "A"program. i put a nikon flash sb 25 in "A"progr and the photos are better the dedicated flash 550.any idea exept to ope every picture in photoshop and take care?

ive been posting things like this since last year when i got my 1d and the 550...still no answers here or anywhere...and a shame that canon has done nothing to address this problem...at the time it was the top of the line camera and its still the top of the line flash and they just dont give you results that you can count on...
if anyone here can get in touch with a canon big wig i would love to hear their take on the situation

thanks
