Using a RED as a Still Camera?

Lately I’ve been messing around with the idea of using my RED camera as a Still camera. It has all the resolution and image to compete with most DSLRs on the market. The new Dragon 6k is going to smoke almost every DSLR on the market. So what is to stop me from using my RED as a full time Picture and Video camera. Shoot tricks and action with the intent of pulling frames for still frames. Was just messing around at the house shooting some photos for my girlfriends boutique. I really want to see whats possible with Flash very soon!
