Just so you all know, I just spent all day with a Canon rep yesterday who let us test a C100, C300, and the 1Dc (we also shot some 5D3, and mushy FS100 footage). He assured me that with the 5D firmware update this spring, we will have uncompressed video that is the EXACT same as the 1Dc in it's "super 35" cropped sensor mode. This was HUGE news to me. Also, from what I saw- The 1Dc even at 4K didn't hold up as well as the C100 with Sound Devices external recorder under controlled light. I'm definitely not poo pooing the 1Dc, but for my needs the C100 is the camera for me at that price.
