I only do video, and I DON'T want the traditional Camcorder / Video style body. Those are super dated and horrible to use compared to the DSLR form factor which is GREAT.
Think of it this way, would you want to shoot stills with a lunch box style body? NO. Video and photo are no different in how you hold the camera. The DSLR form factor allows you to hand hold a camera nicely. The Lunch Box / Camcorder format requires a rig at all times. SUCKS and is super dated.
That is why the C-300 has a more DSLR form factor, because it's where everything is going.
