On the topic of ‘Rolling Shutter’ that Rob mentioned, you’ll encounter that phenomenon with any CMOS based camera DSLR or traditional style. This ‘skewing’ of the image occurs when making extreme camera moves particularly from side-to-side and causes the CMOS chip’s scan lines to ‘overlap’ as the buffered image deals with the already recorded image while the chip puts out the currently recorded image. Because of the overlap, the two images don’t match and you get the optical ‘Jello Effect’ often spoken of. Every test I’ve seen of the latest CMOS based cam’s seem to have come to some terms with RS, however when doing normal camera moves the effect either doesn’t happen or is barely noticeable. Panasonic may have solved this issue, but you may not want to wait to pick up a rig.
Another thing that I will mention is despite the many advantages of DSLR rigs, to properly use it as a video or cinematic camera you’re going to need accessories. Unlike a traditional video cam, you’re using a still rig to shoot video and they never were built with that in mind. You’ll be needing additional lenses, an audio adapter/recorder, camera support beyond a tripod and many other devices to fully take advantage of the powerful capabilities contained within any DSLR.
