Hi, I am looking to buy a camera for weddings and documentary work. We already use 5D Mark II's and III's as we are a photography studio but with the video side in expansion we are looking to buy a more pro camera that will do the brunt of the work and leave the 5D's for remote use or time lapse etc. I know these are quite new cameras but if anyone has any experience with them it would be great to hear it, otherwise by looking at the specs does any one have any opinions? Any advice would be greatly appreciated. Thanks.
