I know it's a bit obvious, but this has to be one of the stories of the last few years. A stills camera that can shoot video!!! I know that there are many variants of this now, but the 5D MkII was probably one of the pioneers and, in my opinion, still one of the best.
I have used my 5D MkII on many occasions and have been very pleased with the results. I mainly use the 24-70 f2.8 lens with it and get some great stuff. You need to learn the best settings to use in terms of shutter speeds, ISO, contrast settings etc etc., before you use it, but you will not be disappointed.
