I have a G1 and am looking at the G3. One of the comments in the reviews so far is "short battery life". According to the Panasonic stats, G1 does 330 - 350 shots and the G3 250 - 270. I do realise that it depends on temperature, lens and so on, BUT in my day to day use spring/summer I am getting well over 500 from my G1 before the battery is run down. (I already have 400 since yesterday on charged battery and only one bar gone). So, in the same conditions would I expect a similar increase on the 250 quoted for the G3 ?
