wrong! they designed it as a STILLS camera, you are shopping in the photography section, not the cinima section. that's what it still is, a photo camera, go get yourself a proper C300 and pay the premium and stop encrouching your wants on the STILLS people.An adapter is fine, but Canon should have designed this from the ground up for video.
I DONT CARE to have a fan on my STILLS camera, it will be heavier, and less weather sealed. I'm sick and tired of these wannabe video people demanding to have everything in a 10000+ video camera from a stills camera.
