Just curious but can't you lock the focus? at a certain distance and then check your zooming, in and out to check for noise associated with motion (in low light), also remember your dealing with a (TINY LITTLE CHIP) back lit or not, its still small and there is only one of them, don't expect a hole lot from a consumer grade Cam in that regard. It seemed to me that you panned from left to right and it started off ok but then it just got crappy as it became much darker. Just to dark of an area, it is outside the scope of ability of these consumer Cam's period. Spend more money on a respectable Pro Cam that is proven, it will alleviate all your frustrations and anxiety's about the sub $2,000.00 Cam's available? Maybe haa?
On a positive note I love what I saw in the 30 minutes I spent at Best Buy yesterday with the cx560v and am actually not going to wait too purchase it. I buying it for my my tomorrow as a surprise. She will be absolutely delighted to get this one, as I promised it to her this summer when prices drop. I'm just being patient for my Canon HF g10 to arrive hopefully in 10 days or so.
