If you are going to balance a camera on your shoulder as opposed to hold it out at arm's length, then the weight isn't so bad with any of these cameras -- a fully-loaded F65 + SR-R4 recorder, etc. is close to 20 lbs, which is maybe only five pounds more than an ENG news camera. As Mike says, what's amazing is how tiny the Epic is, the other cameras are more typical in size & weight. Of course, if I had to carry one in a backpack up a mountain, I can tell you which one I'd prefer... But on a movie set doing the occasional handheld sequence with a shoulder rig, the bigger cameras aren't so bad, especially compared to a 35mm camera with a 1000' mag on it, which is 5 lbs for the film alone.
