I'm making this thread because im suprised at the new Ultra high definition craze. First large sensors for shallow dof and now camera manufacturers pushing the boundries. 8K is just immense, the image quality must be stunning. Its only now when I look at my NEX-VG20 compressed 8bit footage I realise I need one of these cameras.

What do you guys think about RAW and its workflow.

8K (UHDTV) is possibly the future, but it will be a long time coming. The 8K camera is actually 4K, isn't it?

In fact, it is 8k. Presently though its only 4k, Sony will be releasing a firmware update to give it 8k capability, I don't know when this is though.

You're going to be waiting a very long time.

The only 8k camera on the market right now is the Sony F65, if it's even shipping.

Most DSLRs don't even shoot 8k stills.

The only realistic 4k cameras right now are Red and Phantom.

IMO until our motion picture distribution methods (in all their forms) change substantially, it's effectively pointless, circle of confusion renders the added resolution pointless.

Unless people's eyes can actually perceive the additional resolution it really doesn't matter.

One big issue to remember is that this camera is seriously data intensive. The price you pay for UHD. Here's a link to a frame grab from the F65. It's a full resolution DPX. It's near 50megabytes - and that's just one frame... But it's also magnificently sharp and no artifacting is to be found. Shot with F65 and 65mm Masterprime.

The F65 is being delivered and is working on productions (if high end). It's currently a 4k camera, the 8k sensor being used as an oversample rather than being directly recorded. They may wish to directly record the 8k, but it's a Bayer type sensor, so you'd need even more pixels for true 8k, perhaps a 10k sensor.

I suspect Sony will be busy manufacturing the 400 plus units ordered, before worrying about the 8k niche market. Which is different to them researching the full 8k from the sensor.

400? How will Sony even recover the cost of R&D with only that much?

That's the F65 pre release orders, I'd assume they'll have more over the production run. They also cost over $100k each.

Unless people's eyes can actually perceive the additional resolution it really doesn't matter.

The human eye can resolve details down to around 1/60 of a degree of visual arc, assuming 20/20 vision.

For a home cinema set-up, at the recommended distance for the THX standard, 2K is pretty close to the theoretical maximum an eye can resolve. (I did the calculations yesterday, and it came out around 2,200 or 2,400 pixels.) And that involves sitting at a distance of (say) six or seven feet from a 55" screen.

I went to the cinema today, and sitting in the front row of the theatre I reckon the screen filled up 70 or 80 degrees of my vision, so somewhere between 4K and 5K would be sufficient for the likes of me.

The only need I could see for 8K would be on something like an IMAX screen, and if you're sitting in one of the front rows. Given that most people at the IMAX screen in Amsterdam used to sit in the rear half, I'm not sure if that would actually give any benefit. In fact, the maximum viewing angle for IMAX is supposed to be 120 degrees (according to Google), so 7,200 pixels would be sufficient.

Saw a UHDTV presentation at NAB about 5 years ago. Stunnnnnnning. Can't remember anything about the cameras or projection systems, just the 20' wide field of sunflowers and the puddles of drool on the floor. Yup, we'll be waiting a long time.

Don't suppose anyone else was there who remembers what it was? Might have been 6 or 7 years ago.

I heard that argument many, but many times but you are doing a BIG mistake in your logic. Your statement is ONLY true for a static eye and the eye is far from be static. The average human eye has about 6-7 million cones and about 120 million rods. Sum to that the rapid movement of the eye scanning each image and then your math goes through the drain. :-)
This is a math that most of camera manufacturers this days "sold" us so we believe that their products are more than we ever need but this is only part of the story. There is also the time that our retina takes to "release" the information and much more to the subject.
