Well at great expense I purchased this camera. The main reason was to consolidate video and a decent still camera into one package.
Initial findings on the video front are a great leap forward from my Cannon HF100 now nearly 2 years old. Low light video knocks spots off it.. The camera is a joy to use and I an using video more that I used to. On the still image front, the iso is much better and the resolution is 16 million pixels against 12 on the G1. Higher resolution does not seem to evoke more noise either.
As I have only had it a few days I will report back more findings later
