what lens is that mounted on the 4K concept?  I think I'm seeing 7-140mm, but that sounds ridiculous ...

Yea... 22-440mm (35mm equiv.)

Now that would be seriously stunning for sports work!

This is jaw dropping news.

the only issue with a 4K video camera ... is you can't really get the full use of that in playback, at least not on any consumer screen.

and I doubt that's going to change anytime soon, since everything is just recently getting full swing into 1080p HD; doubt we'll be watching Netflix movies in 4K for a long time

Not at all. Have a look at the fancy, already existent Canon DIGISUPER 100AF.
(Which, I have to admit, is built for a slightly smaller sensor - ~1/2" instead of 2/3")

Motion picture film cameras have been shooting 4K plus film for years. That's why 4K is the Holy Grail for digital. Think of this prototype as a digital cinema camera, not as a television camera.

c.d., good point about this technology being aimed more for professional filmmaking ... but the concept design certainly makes it look like its eventually intended for the consumer market, although it will be many years before that tech is cheap enough to get into the consumer price range.  maybe by then we'll have 4K TVs to go along with it

This is all my opinion - I am no expert. I'm feeling to lazy to rewrite it with different phrasing, so I'm just adding a disclaimer.

I doubt we're going to see 4k tv's (there's already a bunch of claims that you can't tell the difference between 720p and 1080p unless you have a really, really big tv, and aren't sitting to far back from it.

But the big advantage is the ability to crop after you shoot the video. Say you film the scene with no zooming. Then later you want that "slow zoom" effect. Are you going to hire a bunch of actors to come back a refilm it? With higher resolution - you just crop in slowly via post-processing. And you don't lose any effective resolution because bluray and hdtv isn't going to see more than 1080p anyways.

Or sometimes something that seemed like a neat effect at the time doesn't work later - you thought slowly zooming in would be really great, unfortunately it turns out that the scene before it and the scene after it ended up doing the same thing, and the effect is now waaaaaay to much and distracting. With more pixels you can post-process your scene to not have any zoom, without losing resolution (because again you started with more resolution than you needed).

Or imagine that you shot it with everyone in the frame, but it's more intense with just two of the people...you get the idea.

If you read the full article... the 4k prototype camera was hooked up to a prototype 4K TV.

With these very large screens, yyou can defeintly see the difference... although I agree it will not be with us for some time (nor will the camera).

4K in the home will be dictated by sports networks. That would require a direct to broadcast 4K camera.

4K (or at least 3K) sounds about right if you want to squeeze as much quality as you can onto an HDTV. As far as I know it's using a Bayer sensor, not a 3CCD or 3MOS. So oversampling then downscaling should give you a great 1080p IQ, certainly better than a Bayer camera which has a native 1920x1080 resolution

Is 4K the same as QuadHD?

In the meantime they could put that sensor into a compact camera body :-)  Maybe combine with some other tech so it that the live view feed is buffered and hitting shutter button grabs a few seconds worth of stills, i.e. you can take the picture of the scene before you press the shutter :-)  Add in the two prism mirror box and voila!

[rant]  Oh great, Canon is spelling it "tripple."  I guess soon enough Canon will start adoping the consumer-friendly spelling "focussed" too as a trademark term. [/rant]

Okay, got that bee out of the bonnet...

I get the "4K plus" film argument.  I think 4K dots of usable horizontal resolution from most film is a bit of a stretch...though the grain gives it a nice character we're not seeing with digital anymore.

I have a bad habit of commenting, every time Philip Bloom points out that PL mount is a necessity for these cameras (or at least for professional acceptance of them), that Canon probably doesn't plan to use a mount standard they don't control for such a camera.  The interesting lens on this concept camera bolsters that argument...only a day after I dropped a thread in the Lenses section with no replies - well, good timing on Canon's part.  In all seriousness I would like to see autofocus tilt control in lenses...but that's for another day.

On the 4th picture, 2nd man on the right, as I can see standing between Chairman & CEO Fujio Mitarai and President & COO Tsuneji Uchida, is our Chairman Board Executive Directors of the dutch Canon-Océ: Rokus van Iperen.
Canon is working realy hard now it seems, will be exciting times for us to come.
