It's a bit ironic that the hpx300 has a great form factor for fast mobile handheld and other movement. And yet it has a CMOS sensor with a rolling shutter. There's things that can be done in engineering that can minimize the effects of wobble and skew in a rolling shutter, and most likely Panasonic like other manufacturers has done a good job of it. Perhaps better.
The SI-2K has a CMOS sensor and a rolling shutter, and when I was watching Slumdog Millionaire, I never noticed wobble and skew and this was a movie where the camera was constantly moving, panning, etc. I did notice the noise, but it fit the aesthetic and the vision. I was engrossed in the visual story telling and drama.
So for me, the technical differences between global/rolling/CCD and CMOS are not significant enough that I would prioritize them above dynamic range, resolution, mobility, ergonomics eyepiece placement, and all that other good jazz.
