I purchased this camera with a sandisk 2gb standard sd card since the "ultra II" model had bad feedback and the "extreme III" is limited at 1 gb only. Unlike many reviews says, with the standard speed card I still can shot on infinite burst mode (maybe not at 2.1 shots/sec but not also too far from it) and use the movie mode with highest quality (640x480, 30fps).Overall, I'm very satisfied with this camera. The noise problem, maybe the biggest users complain, does not affect the final quality of the pictures if you properly care about light conditions, exposure and ISO settings.
