PowerShot / Re: New PowerShot G17 Coming in Spring [CR2]

It requires a minimum aperture of 31mm = 168 / 2.7 / 2 (2.7 being the crop factor of 1 inch sensors). Not small enough to be a compact camera but not too big to be impossible.

EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs

I would bet on a resolution of 8712 x 5808 then.

It makes 50.599 MP and each axis can be divided by 24 (3 * 8)which is convenient for binning pixels together (software-wise if not hardware-wise)

EOS Bodies - For Stills / Re: POLL: Do you need 1/8000s shutter speed?
« on: January 06, 2015, 05:27:07 PM »
1/8000s is quite useful to me in order to shoot with fast primes on sunny days. I would even be happy to get a faster shutter speed sometimes.

According to a quick lightroom EXIF search it corresponds to 2.5% of my shoots. That's more than once every 12 months on my side.

It is stuck at 00:00:00 ... that's disappointing!

EDIT: All right the script is timezone specific according to previous comments, meaning it won't display the right coutdown for the ones of us in Europe.

8K resolution would just fit in the 44.7MP:
Taking into account the 3:2 aspect ratio, it would make a camera of 8192x5460 pixels, allowing
- 2x2 pixel binning for 4K recording
- 4x4 pixel binning for fullHD recording
- full pixel use for 8K imaging

44.7MP sounds too great to be true!

IMHO the 44 MP will be a 22MP = because of the new focusing system. Remember 2 pixels instead of one?

Now that monster 75 MP - it most probably will be a 44 MP for real. Having that amazing focusing system.... now we are talking. I am looking forward for the ISO improvements though.

The Dual Pixel CMOS AF splits every single pixel into two photodiodes, so it looks to me it is a 44.7MP with 44.7x2x3 million photodiodes (x2 for dual pixel, x3 for 3 colors).

Looking at the 70D sensor of 20.2MP and taking into account the 1.6x crop factor, Canon could reach 51.7MP with the same tech as for the 70D.

So 44.7MP with Dual Pixel tech shall not be too complex to bring to the market in terms of sensor technology. This year for the C series and maybe next year for the rest of the line.
