The Red bubble is bursting and Arri, Canon, Panasonic and Sony are already ahead so I can't see any reason why someone would want to buy a Red camera these days. Even the smaller Kinefinity, Z-cams and BM looks like much better alternatives.
Red consistently ranks in the top three digital cinema camera brands. The image quality, dynamic range, color science and workflow are top notch. Their sensors are recognized as some of the best on the planet. Panavision bases their top of the line camera on Red technology.
The low end market cams have certainly gotten much better, but they still can't match the IQ of Reds in skilled hands.
