Well done Apple and that's from an Android man!

Image enhancement by software is only just getting started. As the processing chips get more and more powerful, who knows what will be achievable.

It was like he was holding his first born! But yes exciting times for us photographers. Great video.

That's 8,000,000,000,000 bits!

Maybe the camera that sets the tipping point for MF. But personally I would have preferred a compact fixed lens model.

Sony now vying for 1DX, 5D and D5 market, maybe the E-mount is dead?

It would take just one fast prime. . .

Canon I know you don't do 'hurry', but maybe you could add a few fast primes?

All cameras should have had Global Shutters by now!

Red and BlackMagic already have global shutter sensors. The rumors of Panasonic 'any day now' have been going for years!

No in practice nowhere near 6000 AtoD's are required. In fact because pixel binning and the dreadful line skipping the data rate is reduced.

However, the AtoD's cleverly employ a pipe-lined architecture. This actually time shares the data column workload between the convertors. i.e. the convertors don't operate independently. I'm moving out of my depth now, since this is where the really clever stuff occurs and is not my field.

'Andy' they do not need to operate that way. Charge data is read out in columns to banks of AtoD's. Further, It can be safely assumed that a 10us Global shutter does not have any visible image rolling effects.

Assuming say 6000 x 5000 pixel sensor, it would have to convert 5000 bits of data in 10us, which equates to an AtoD speed of 500MHz. That's nothing these days, but with so many of these integrated onto the CMOS sensor chip, heat is the obvious (remaining?) problem.

Once this data is latched in parallel to buffer memory, there is plenty of time between frames to serially off load this to the memory card.

Obviously, this is an over simplification of the process, since I haven't accounted for all the clever noise reduction techniques that each manufacture employs.

No disrespect to Canon, but they have been slow to the market and it has to be said that the 2014 Samsung NX1, but sadly now defunct , still sets the bar for the most advanced (Consumer) sensor.

Sorry to disappoint 'Nob Head', but I'm a electronics R&D engineer with many years experience in ASIC design. May I suggest in future that it would be prudent to check before making a disparaging comment.

4K compromised with a 1.64x crop. What a waste from that lovely new sensor.

Maybe Digic6+ is not up to the job, or is it just protective marketing?

When I was at school I had a Saturday job in a TV shop here in the UK.

The first colour broadcasts had just started on BBC2 and I marveled at this. I would happily fiddle around the back of theses valve (tube) sets trying to perfect this colour, but I remember all our customers were amazed.

8K just bring it on. I think we will be amazed as well:-)

Just Googled 'Getty extortion letter' and up popped over 100,000 results. A revealing indication on how they operate.

I love the contrasting Aston Martin to the old Volkswagen badge. Nice touch.
