Oops should be 8 million frames per second!

In respect to filming nuclear explosions...Rotating mirror cameras run at the rate of 8 minutes frames per second but only can record a few hundred frames. A strip of film remains stationary and a hexagonal rotating mirror running at 10000rpm wipes the image across the strip.

What is the bit depth of the JPEG video?
The reviewer only makes negative comments about a 500mbs recording ability.
In the world of pro video low compression is a positive feature!
1/So have Canon gone for 8bit or 10bit jpeg Video?
2/Does the dual pixel raw turn this camera from a 30MO sensor to a 60MP sensor?

Why should canon be a sponsor, the equipment was trivial aspect of achieving the result. Cameras don't take pictures, people do...

From the period 2000 to November 2013, worldwide, no members of the public were injured by a helicopter or fixed wing engaged in aerial filming or photography. 150 crashes with scores of death and injury to crew but, surprisingly no public injured in any of these incidents.
The opposite is true with drone use, where pilot and cameramen are at less risk than the public.

Sadly, in March 2014 in Seattle a member of the public was killed when a news chopper toppled from a rooftop heli deck.

8k broadcasts spec is 120fps, so a typical shutter speed will be 120-240/sec

So digital Camera manufacturers have to adopt 120fps.
Sony at nab 2016 launched a 4K broadcast camera that can output live 480 fps in 4K. It is designed to output live 4K and HD signals at 30 and 60hz simultaneously as recording 480fps for slo mo replay.
Do the math, 480p at 4K is the same data rate as 8k at 120fps.
Plenty of 8k lenses, existing OLED and LCD can be scaled, third gen NHK funded Astro sensors will do 8k at 120fps.

So the prices of the jigsaw are coming together, ahead of schedule.

If you want to sit the same distance from a 8k screen as you do watching 4K you won't see a difference?

The point of 8k is not to do that!
Think of screens sizes via projectors, glass screen or goggles that are 4x larger than 4K, in respect to how they fill your field of view.

If you drive a Ferrari at the same speed as a Hyundai it won't be any quicker:)
Watching 8k on such a screen is like watching an event through a window.
At the turn of the century the next planned stop by NHK from HD broadcast was to be 8k. 4k was not considered a big enough jump.
Digital cinema stepped in and adopted 4K.
They'll do the same with 8k when the price is right. So expect a viewing experience via goggles or large screens, perhaps even small booths, to take advantage of the amazing experience.

I want to use the 7series with super telephoto lenses that do not have inbuilt stabilisation.
When using third party lenses does the sensor stabilisation still work? In other words does the 5 axis sendor stabilisation work independently of the lens?
Will the new 7II be the same?
Do any other dslrs with sensor stabilisation work with manual lenses?

Thanks

Let me put the specification and price of lens in the context of its target user.
Canon built the lens for use by professional cameramen and DPs and TV sports production.
Some cameras that will go on the end of it cost more than the lens.
The lens will have a usefull life of at least 15 years.
The lens at $800-$900 per day (3 day week)
It out performs the Canon 150-600 century precision optic lens ( a reworked canon 150-600)
The lens is relatively light, it doesnt need a massive tripod and head.
Its speed is a compromise on weight.
A set of Summilux primes is $300k, a Optimo 24-290 is $90k. A HD sports zoom lens is well over $100k.
The 20x50 has already been used in stabilised aerial gimbals which themselves cost $450k.
So the $$ cost is in line with cinema industry norms,

A faster lens would be a compromise on mtf and heavier which rules out its use in gimbals and for wildlife.

So canon have got it right!
