Guys, Guys, before this breaks out into all out war
Right, General concensous is that the 550D is the better video dslr. Right, have that. My question was at the begining and is now (sounds like mass) was that if my friend got a K-X and had access to roughly €2Ks worth of my lenses, would that be a better option? A few of you have shown me that the K-X is quite a capable little video dslr but the Canon does have undeniable advantages. Anyway, long story short, this arts course is practically based around the 550D so he'll have to get one. Now because I refuse to believe that my Limited glass won't be an advantage, I will get a K-5 and shoot alongside him while making a couple of 5 min movies. So in 6 months time or whatever we'll both post our finished videos and everybody can make their own mind up.
Thanks again everybody for giving me tips and options and advice. All greatly appreciated.
ps, i'm not getting the K-5 purely for this, I'll be using that for available light photography and low light portraits which I enjoy immensely. I'll also be keeping my K20D because I have to see for myself if the K-5 can actually compete with it in low ISO situations
