The battery life on the *ist D feels similar to me. I rarely charge it. One big thing about digital SLRs is that the image sensor spends a very little amount of time turned on. This is different from P&S cameras where the users are typically using the CCD and LCD as their viewfinder. Given the tiny amount of itme that the sensor spends turned on I don't think that it makes a huge difference in battery life on our cameras. alex
