In spite of the downturn economy my company has been closely researching camera models to augment our existing HD workflow. So far, the one I keep coming back to is the Canon EOS 5D MkII. The only other camera in the same weight-class when it comes to video imagery is the Red Scarlet in that it can shoot in film resolutions of 3-5k. But to achieve that you will spend tens of thousands of dollars to do so. The Mk II however shoots 5k natively in addition to Standard Def, can accept any EOS style lens ever made and you can get the camera body, starter lens, battery and compact flash card for the price of a full Scarlet kit that only shoots 3k. Now since it wasn't designed primarily to be a video camera there are some 'adjustments' the non-photographically trained videographer will have to make to use it. Fortunately, Canon has heeded user complaints and instituted firmware to allow manual control over the video and there are issues concerning sound aquisitition. But overall, it's really looking like a viable option.
Here's a video from Mac Video's Rick Young who give a thorough review of the camera and the systems by redrock micro to make the Mk II both cinematic and videography friendly. To my fellow PC users, just put a chunk of wood between your teeth when they start talking 'macie'. Be advised I'm a crossplatform guy.
