32? 36??

8k is 7680 horizontal and 4320 vertical.

7680 / 4 = 1920.
1920 * 3 = 5760.
7680 * 5760 = 44.2Mp.

?
8K width X "6K" width? Why?

8K width X 8K height is still 7680 (4x 1920) x 4320 (4x 1080). That's 33.2 Mpix, or if you define it old school. 31.6 Mpix (generally rounded to 32 Mpix).

Kind regards, Wim

Uhmm, no. You certainly do not get it.

8K width = 7680 pixels.

So, what is a 4/3rds sensor? 4x3 aspect ratio.
7680 x 4320 is 16 x 9, not 4x3. MFT is called MFT (MicroFourThirds, not MSN (MicroSixteenNineths))...
Now calculate how many MP the MFT sensor needs to have to do 8K video.

Indeed, exactly as I showed you: 44.2mp.

I actually did get that, but the question is whether a video-cam at 8K really needs 44 (or 42.3 old style) Mpix, or more specifically a 4:3 layout. It can still be a 4/3 sensor in size (diameter), and have an 8K layout. I should probably have been clearer on that.

So far, I've only seen it announced as a 32 Mpix camera, when a number is given, so I guess we'll have to wait and see.

However, density-wise it would indeed be a 42.3 or 44 Mpix sensor, so a bit over twice as dense as current implementations from Panasonic and Olympus.

Kind regards, Wim

The camera clearly is not a video camera, but a photo camera with 8K video (see form factor).
What makes MFT is the 4x3 aspect ratio.

What is the diamater of a rectangle?

It is about the diameter of the (usable) image circle, not really about the diameter of the rectangle, AFAIAC.

Just for reference - the 4K Blackmagic MFT camera has a sensor size of 18.96mm x 10mm.
I suspect that Sharp will follow that approach (given the similarities in design I wouldn't be surprised if the Blackmagic camera is actually made by Sharp).

This indeed.
