After having checked it just to see that it worked, I have NEVER used auto bracketing. If I have a situation where the camera is underexposing the main subject (e.g., typical backlighting situation) then I increase the exposure appropriately. If the camera seems to be overexposing, with important highlights being blown, then I will make exposure correction in the opposite direction. Most of the time, the exposure is correct. When it's off I can tell if it's over or under, and I don't find it necessary to take an extra shot with exposure changed in a direction that I know will make the problem worse. If it's an underexposure problem, I would rather take two or three extra shots to compensate for it, going to, let's say +1/3, +2/3, and +1 than having the camera do +2/3 and -2/3, when I know that -2/3 is just going to make the problem worse.
It is supposedly 'in the works' - You would think that Canon would have to come back with something to counter the new Olympus. Most people on the forums are going by the old release dates/months and saying it will probably be announced in Feb. this year. It's really speculation and so are the specs and even the name (S4IS or S5IS?) ... probably S5IS if it happens (the number 4 has a negative meaning to some so Canon may jump to S5IS) You should see the wish lists people have for the S3IS upgrade!
