We were at the Capital Circus of Budapest at weekend for the new show which will be playing from Oct 3 to Jan 3, 2010 (fnc.hu). It was a really great spectacle, don't miss it if you visit Budapest in this period.
The GH1 handled this kind of lighting pretty well, however not as good as I expected. The low codec problem is seen especially at red channel. This was filmed with kit lens and ISO 1600. Sound is from the camera built in mic. No CC. The performance of the camera should increase significantly if we use fast prime lenses and max ISO 800. Unfortunately my prime lenses was not in my backpack that time, but I think is a good test to share how performing the camera in stage light with the kit lens.
