I definately dont think its a hinderance ..
In fact its a great camera... I want to get serious, but im thinking if im going to get a HD video capable one, i might as well start builing a kit and skills around the new one.
I actually bought the Pentax K100D from a forum member here (i dont know where the for sale forum went..) but he had won a few comps on Ausphotography with the shots he took with the K100D.. very impressive.
