I'm not sure how 16 bit 4k raw at 120 or more fps is hobbled?
In the digital world there is always a what if.
The sony looks good on paper, but the proof is in the file. They and everyone talks about film like look from the $1,000 to $40,000 cameras.
But . . . I really do hope the F5 works for you though it's 16 grand for the body, plus and 5 grand for the 4k storage box, (which is to come), 5 grand for the oled viewfinder, and a "Z" mount lens at 10 grand.
That's $36,000 or so, and that's a lot of coin. Heck I bough two GH3's and Olympus and a box of lenses and didn't top 6 grand and have touch screen autofocus.
Even dropping the lens form the F5 equation this is beyond Red 1 territory and weighs as much, as I can get an R1 with Nikon mount and lens to about 8 1/2 pounds.
Not saying it won't work, but there is those dirty little words, "to come".
I've been there, done that, bought cheap and expensive and there is always another shoe to fall.
I'm glad the F5 is here, it helps all of us, wish it was the fs100 price (where I really believe the high end price should reside) and btw: whatever happened to the fs700 4k upgrade?
Anyway, I kind of get the feeling that Sony and (more companies to come) looked at RED's price list and went ah-ha, that's the magic number, or better/worse looked everyone in the digital world's annoiunce to deliver process and said "announce something first like 4k, we'll figure it out later" cause they'll wait for the tires, they already bought the car.
