I am sure the only reason the 1dx doesn't have sound sampling (other than bars) is a nod to Canon's video division, since the 1dx has high iso and down samples from the full sensor which is suppose to eliminate most moire, which would make it a competitor to Canon's own c300.
If this is a real price drop on the c300, I'm also sure it's a nod to the Scarlet and the Sony F3.
But when it comes to indie work, I think a lot of people are forgetting what a massive third part industry there is for hdslrs. Sliders, cages, wheels, mikes, time lapse, steady supports, software, lenses, PL conversions, hdmi to prorezz on the fly transcoding . . . and a million more things I haven't listed.
Indie guys love the dslrs, because the buy in is low and the form factor is small enough to use a lot of third party parts. I know before buying our REDs I spent almost three times the price of our 5d2, just on these parts to make it really useable and still didn't have the video file I needed for grading.
Maybe the 1dx will overcome this, maybe the c300 will be even better, who knows until you try it.
I do know that in the Canon league price is a major reason for buying and I'll bet they sell 20 1dx' to every c300, maybe more, unless the next 5d is something amazing, then canon will sell nothing but 5d's.
But even at the 5d price buy in, by the time you get it to work in most heavy production, your into almost serious money and the camera is probably a 2 to 3 year deal until some dslr maker comes out with 3k or 4k raw, then all of these cameras that shoot a baked in file will go on the shelf.
We can talk 4 color pixels to one all day long, but at the end of the day, it always comes down to price and usability. I think most people expected an raw file option, autofocus mount combination 5d2 and RED killer at under $10,000 and instead they got twice the price with singular mounts and less usability.
I still think if your going to buy at the 20 grand range, a MX sensored RED One will be more usefull and last a lot longer than the Canon . . . but that's just my view, others will probably feel the different and we'll know when the dealers start talking about sales.
Time will tell on the c300 and I hope I'm wrong, but I have a feeling that Canon didn't have the ear to the ground on this one.
IMO
