nah man, ever since 35mm adapters came out one of the main selling points has been shallow DOF, the manufacturers always made a point of mentioning it in the product description. it only seems like kids are going crazy now because it's affordable.
to OP, everybody else pretty much covered it. but one of the downsides to DSLR video is that zooming is really difficult and just doesn't work that well. Pretty jerky on even some really nice lenses
