I call it MCC or module camera concept, by choosing an dslr, you are separating all the different modules that make up a video camera into their different components. Like the lens, Audio, recording system, chip etc. If you have all these modules separate, then you don't have to replace the entire camera when it comes time to upgrade. All you do is replace the module that has become absolute. http://newagetv.co.za/videographer/why-i-switched-to-dslr/
That's why dslrs are cool.
