Hitachi shows 8K S35 camera at NAB

What price is this going to come in at?
Nowhere near what us mere mortals (even those who can afford Red gear) could possibly afford.
 
If we assume that today cutting 4K is relatively affordable, by Moore's law we will have 8K ready, affordable machines in 4 years time. So as NHK predicted: 2020.
 
I suppose they are trying to make a Tier 1 UHD camera according to new broadcast standards. In order for it to be tier 1 for UHD content, it has to have at least an 8k sensor since the standards state that it has to have 3840 x 2160 for each channel of RGB. So 8k cameras are actually designed for 4k delivery according to the new broadcast standards.

Accordingly, the only cameras out right now that are able to be approved for tier1 UHD broadcast content globally are F65 and Alexa65...and soon, red weapon 8k. But it looks like there is a new contender. Certainly curious.
 
Yep 8K=Tier 1 UHD / 4K Cameras.
8K is for 2020 Olympics.
It's coming and it's not overkill. It's needed.
 
4K RGB is 26.4 MPX, which is less than 8K. Technically speaking, neither F65 nor Alexa65 has a 26.4 MPX sensor.

In any case, I am sure they're going to test 8K at this summer's Rio Olympics and try to get a live 8K transmission for the 2018 Winter Olympics in Seoul.

Price-wise, if ya hafta ax ...

The standards as it has been layed out is a bit tricky. But the logic is that because for tier one is chroma sub-sampling of 422, that the two cameras I mentioned meet that criteria because some interpolation would be allowed. And yes, they also say that 7k, 8k and 9k sensors should be able to meet this criteria. Anyways not my opinion.

My my words are by no means the final words on this, but it is good that broadcast standards are taking into accound bayer patterns and CFAs on cmos sensors. BTW, these EBU standards seem like an innitial attempt, but many people are pointing out potential flaws. It'll be interesting to see how it evolves.

Interesting. But... pointless? We already know that there's no point in even projecting beyond 4k, we humans can't see it. The great majority of DCPs are 2k.

I can make a case for 4k captures and HD/2k delivery. I can't see a need for 8k at all. For anything.

There's a lot more I want from a camera beyond simple resolution. I want more dynamic range. I want better tonality, especially in the highlights. Graceful clipping so I don't get color casts in highlights. I want less noise in shadows. I could go on, but my point is that more resolution ain't on my list. It's just not.

That is correct. A "normal" human eye can't tell 4:2:2 from 4:4:4 but, technically speaking, RGB is still 4:4:4.

BTW, A6300 has the highest oversampling of any of those cameras (because I don't believe NX1 has a full readout) with 20 MPX. Of course, its rolling shutter is horrendous but, at the same time, it's a $1,000 camera ... slightly lower priced than F65.

You've shot an ad - it can be food, clothing, whatever - and a major department store/mall/exhibit will show it on an 85" 8K screen in some sort of a pavilion, with people being able to walk a foot in front of it. At this level, you want as high a resolution as you can get.

First rule of sarcasm - never include a smiley face.

Just speaking about the tier one standards which accept 444 and 422. Not sure if there is any misunderstanding here. But you have a good point, I'm jumping ship to the A6300...because it's slightly lower priced.

Good one. Funny, I looked for a smiley, but I didn't see a winking one, though I admit to spending a whole five seconds looking.

Nah. This is like Steven Wright's delivery. You have to be dry. No winking

And this is how it's done (of course, I never said that one should abandon F65 to purchase A6300, so the jab missed its target by two F-stops).

We can and quite easily. All you have to do is output a red circle and a blue background. Or vice versa. You output that in SD and it will look twice as bad.

Also GUI elements will look quite bad with a 4:2:2 output. There are 4k monitors that can only show 60p by doing 4:2:2 and if you use them as computer monitors, you will notice it.
