certainly not , but they did beat Canon to a sub $1000 device.... after all, my comment was about the part above bolded and in green, and neither the C500 or 1Dc is inexpensive..http://www.forbes.com/sites/paulmonckton/2015/01/13/4k-video-on-iphone-6/2/Quotehttp://www.usa.canon.com/cusa/professional/products/professional_cameras/cinema_eos_cameras/eos_1d_c
And when you step into those two models, you're in the RED Scarlet price range
Which you previously showed to be within your budget. Canon makes 4K Raw cameras. What you want is an inexpensive Canon 4K rig. Assuming the thermal design of the rumored body is adequate, I don't see any reason Canon wouldn't enable it (as at that point it would be largely software).
Either way, the notion that an iPhone will record 4k before a Canon camera is demonstrably false.
[If video were my thing and I had the budget, I'd go down the RED path too]
Do you believe it was announced before the C500 or 1Dc?
and all that said, I would be willing to bet that the video from something like a 70D up-sampled to 4K would beat any video coming out of an iPhone.
