Think of it this way... you can use a screwdriver to bang in a nail, but that doesn't mean it was intended for that purpose. Or more appropriately, in this case... you can use a ROCK to bang in a nail...
AH BUT as any professional joiner will tell you you use a hammer to bang in a screw the slot is only for taking it out!!!!
I really can believe the venom being spouted here however one thing does puzzle me since it is so obvious that a Nikon is much better for this sort of photography why piss into the wind about a Canon not being so well specified - if this is your forte change your camera to the one that does what you want better/easier. Going back to the good old days out and about it was a motorised Nikon 35mm with a 250 bulk film back and in the studio it was a Hasselblad with film and Polaroid backs now both would have done the others job but with a bit of hassel and being a professional and a lazy one too one chose the best tool for the job. So while i find this thread interesting i am not convinced that it is not just a rant at Cannon which i find difficult to comprehend as speaking to Canon direct 'could be' much more productive. And if two people do this - then they might think.......but if just a hundred or even a thousand people do this then they might notice and make the changes you want to the firmware in their camera. There you go start
The Canon HDR Movement and see what/where that gets you - posting here is obviously highly frustrating for you as few seem to get the point you are making OR read your first posts and reply in a sensible manner.
