4K 25p just announced in a firmware update for April.

Thank you !
I am not an expert but the general questions for me are: 1) Does the line skipping work ? My answer, not well. 2) Does the 1DC cmos reading technique work ? It seems very well from the first impressions on the web 3) Why other manufacturers of full frame reflex do not follow the 1DC cool concept ditching, at the same time, the line skipping ? this is a mistery to me. I really do not understand.
And in fact when Canon has decided to make a very high quality video reflex has abandoned the line skipping judging the technique not up to the task, at least this is my belief. And also, why not adopt the same technique also for the existing 5D if technically feasible of course ? From what I understand is mostly a matter of different firmware and some hardware modifications, nothing that could not be done and quite easily I imagine, but if I am wrong tell me please. To go on with a "fundamentally" flawed approach (i.e. line skipping) sounds even perverse to me. I think we cannot honestly ask to Canon to change their commercial policy, but I would expect that other brands like Nikon for instance will adopt this reading technique and provide extremely high performing video reflex. I think they could do that without particular problems and even at a lower price than that of 1DC, as Nikon does not have camcorders' line sales to defend. In the end it seems that the difference between the 1DX and 1DC is just a different FW, from what I read. A very expensive FW indeed. To end, my feeling is that the video market is not completely developed, differently from the photo market. Nevertheless I think this 1DC will show the way and others will follow, pretty soon. Thank you very much again for your technical advice. Regards, gino

Hi ! I think it is an extremely interesting product this 1DC, as a concept I mean. If I understand well Canon has abandoned the line skipping technique used in the full frame 5D for a different strategy of reading for the cmos sensor. And it pays a lot, at least so it seems. This is a very nice achievement. Regarding the price I think that quality level is a little subjective, certainly more than price of course that is very objective. Canon must also defend their own camcorder models, like the c300, just to avoid an internal fight. The 1DC should be priced just lower than the c300. So I assume that the video quality is almost equivalent. But the very very interesting outcome for me is that a really high video quality is indeed possible from photocameras, if correctly designed for video of course. If only this original cmos reading strategy were more widely used the world would be better Line skipping is bad. Kind regards, gino

@ahbleza When I open that page, the video on it says ""the creator of this video has not given you permission to embed it on this domain" and I cannot play it. Is anyone else having that issue?

@Xenocide38 I see what you mean, but only up to a point. The difference is a lot bigger at the price points right above and below it, including 1080p 60fps from Sony at close to half that price, or the GH2 at a 1/3 to 1/4 of the price. And for a little above $2500 the ISO performance has drastically improved (and for a little more than that you have the FS100).

The biggest differences during that time frame have been seen in the $500-1,500 bracket and the $4,000-10,000 as opposed to the space between them.

So 4 years ago we got a camera that did 1080p 30fps 4:2:0 H264 video for $2500. Today for $2500 I can get...practically the exact same thing. 4 years and every "upgrade" means an upgrade in cost as well. Everyone has a price bracket and guaranteed people will buy items in that price bracket if something NEW is offered (ex. new iphone every year, same price, new features).

@DisneyToy Don't forget that 4K is only listed as a future upgrade for the Sony. It is quite likely that they will charge for it, like they did with their log mode on one of their other cameras recently. And the price for that upgrade and the external recorder it seems likely to require at this point is unknown - it could meet or exceed that $15,000 price, though it seems likely to be lower.

As far as 2.5K, it is not sexy to market. HD, 2K and 4K all have marketing sex appeal. 2.5K sounds like an engineering term, and makes people wonder why they don't spring for 4K. :)

Vitaly the info i posted is based on the canon oficial launch page.

About APS-H crop in 4K mode.

1Dx sensor is 5184 × 3456, so crop is absolutely natural to have 4K horizontal pixels.

Where is the pricing info at? I don't see it anywhere on those links?

Nonetheless, as others pointed out: no RAW workflow? Why?

EDIT:

• No articulating screen.
• Screen has a 3:2 aspect ratio.

Overall, the C500 seems a lot more exciting, unless there is a very noticeable advantage in high ISO video performance for this model.

@No_SuRReNDer Well said.
