I'm sure this is true. I'm sure we'll be seeing smartphones that can take 8K video in the future. It doesn't matter if it's necessary for anyone. That's just how things evolve. I'll bet 10 years from now, televisions will be 8K or higher and backward compatible with earlier formats. You'll buy one because that's what they're selling. Will there be widespread 8K broadcast/cable/satellite TV by then. Who knows? I'm not going to lose 1 second of sleep over it. If I see something that I think will benefit me in some way now, I'll consider buying it. If not, I won't. Having an 8K TV without having anything to watch in the format wouldn't interest me,and I think that those who rush out and buy the first ones available are going to waste a lot of money for nothing.

The question is always who is going to flinch first. With nobody buying the TVs who will produce content? Without content, who will buy the TVs. There are usually enough folks on both sides of this to get any good innovations off the ground.

VR will destroy those minds and personal relationships before they get to the holograms...combine with legalized drugs, gaming and general moral decay and you can put a fork in our society...

"Pluckin' those 33 megapixel stills from 8k video at 120 fps video will be so fantastic... "

Yup!

A question: How many of us are producing television programs for the
networks or major cable channels? If you're not doing this, 8K video
is completely unnecessary; just one more way the manufacturers
create a need where none exists. I'm sure the GAS people will be
breathlessly waiting for the Big Brown Truck to arrive. Not that long ago,
4K video came out, and top Hollywood producers and directors lauded
the quality as "revolutionary." Did I miss something? Has 4K suddenly
gotten worse? I think not. So as we say in Brooklyn, "FUGGEDABOUTIT !!!"

I would welcome 8K in movie theaters. 4K is okay. There is still something lacking when compared with film. (I'd still rather watch 4K over film with the jumpy projectors and damaged prints.) As far as at home, I agree. Who needs it? If and when it becomes a standard, just like 1080p, we'll be using it anyway, but I don't feel any compelling need to jump in any time soon. Someone else can waste their money.

Yeah, that’s a reasonable alternative!

Who says that?

Many have used the example that there are "sharp" billboards made with iPhones. Viewing distance is the key. What kind of photos are you talking about, photos to hang on your wall? Which camera did you use. Just curious. I've never seen anyone make the statement that you can't make a sharp 4 foot photo with a digital camera.

I saw a 8K TV relay of the Olympic Games in Rio de Janeiro, Brazil (filmed by NHK). The image is spectacular but the TVs have to be huge (the one I saw was 300 inches) plus there were 22.2 audio channels !!! The standard is not even in the radar for the US. Not sure how photo would benefit from the 8K standard.
4K is ok but the difference to 1080p is really in HDR which is really a candy to the eye!

What do I think about going to 8K? As a personal opinion, I think we are into a bragging rights only area. We now have 4K which doesn't even cause most cameras to work up a sweat. 4K looks like a photo on a 60" set. (I have two 40" TVs). I'm currently sitting about 18" from a 27" computer monitor with 1920 X 1080 (1080p) resolution. That's approximately 2,073,600 pixels. A 24 Megapixel sensor is over 11 time that. What is the number of pixels in an 8K? 4K is 2160p. 8K is roughly 15360 X 4320, or over 66 megapixels. If I did the math correctly. Many, if not most receivers have to upscale to get 4K. Where will the bandwidth come from to handle these huge signals without a lot of compression? Off the Air (OTA), satellites and cable do not have the bandwidth to handle these signals without modifications to both the hardware and regulations. Yes that compression is available, bur is there a lossless compression? The saving grace is with digital displays, they only need the information to change the pixels that change, rather than redraw the complete frame although it can cause artifacts.

Why go to 8K? What will be gained? Except for very large screens, no one will see a difference! Only where a lot of people are watching it MIGHT make a difference, but who sits close to a 100" ot larger TV?
There is also a buffer problem handling large data throughput. Shoot a number of rapid fire shots with a 24 to 30 plus megapixel sensor. You quickly run into a full buffer and have to wait.
The D810 will shoot 4D, but at the full resolution (which is more than 4D) it still is limited by the buffer. The D800 will shoot 1080p. At 1080p that is many hours of recording on a tiny 64 GB memory card. With an adapter you can up that to 128GB. Better carry lots of batteries.

Cameras with full frame sensors are heavy! It's likely an 8K sensor can be made to fit the 810 size cameras, but what is the diffraction limit for lenses used with full size sensors? My D800 can use the same lenses that my D4S used. I still remember hauling a TV "mini cam" around.

To me, going to 8K makes about as much sense as a 24 MP sensor behind a 1/8th inch lens on a cell phone or monitor viewing angles beyond useful.
I have no need for 4K let alone 8K and my D800 gives me more resolution than I normally need.

I think it's clear anyone who shoots video would want a 4k or 8k or 16k camera. When you down-res your video to 1080 or smaller it will have advantages over something shot in 1080.
Plus pulling stills from your video will be awsome.

If you record in 4K and sub-sample to 1080P, you improve sharpness.

If you record in 4K and edit to 1080P, you can crop down to 1080, and you can take advantage of software image stabilization if you framed loosely enough.

Those same advantages are magnified at higher capture resolutions...

The higher the resolution of a video capture, the bigger the still images you can pull from it.

Onward and upward... Bring it!
