NHK working on 8k video sensor capable of 120fps
Japanese national broadcaster NHK has said it is developing a sensor capable of shooting 8k video at 120fps. It will be able to support the company's Super Hi-Vision standard of 7680x4320 pixels (generically known as UHDTV) which, at 33MP, is 16x higher resolution than current 1080 HD technology. The high-speed chip is being developed with Shizuoka University and was reported at the IEEE Internation Solid-State Circuit Conference currently taking place in San Francisco. (via The Verge)
UHDTV is expected to arrive in homes some time around 2020 (the first screens have been demoed) and a 60fps version will be used to show high-quality footage from the 2012 Olympics on a series of large screens around the UK.
NHK has a history of developing high-resolution broadcast technologies - having started producing HD content as far back as 1982. Previous 60fps 8K cameras developed by NHK have been based around multiple 4k chips from Aptina.

No Nikon camera we've tested to date balances stills and video capture as well as the Nikon Z7. Though autofocus is less reliable than the D850, Nikon's first full-frame mirrorless gets enough right to earn our recommendation.
Nikon's Coolpix P1000 has moved the zoom needle from 'absurd' to 'ludicrous,' with an equivalent focal length of 24-3000mm. While it's great for lunar and still wildlife photography, we found that it's not suited for much else.
As a stills camera the Fujifilm X-T3 is a pleasant update to one of our favorite APS-C cameras, significantly improving the autofocus. If you're interested in stills and video, though, it's knockout.
The Nikon Z7 is slated as a mirrorless equivalent to the D850, but it can't subject track with the same reliability as its DSLR counterpart. AF performance is otherwise good, except in low light where hunting can lead to missed shots.
The Canon EOS R is the first full frame mirrorless camera to use the new RF mount. We're well underway putting it through our range of standard tests – take a look at how it compares to the competition and our thoughts on using it so far.
