8K MFT camera by ... Sharp! - Klaus - 01-09-2019 https://m.youtube.com/watch?v=algDFH8u9DA&time_continue=182&ebc=ANyPxKrNMAkBLkkJe2oienMyX4ldRm6UXexPTSCxoV56XRHV8xjUQjLnIFuncuVd4HgEezdtVybqrBTBXL_eNSU3sn1bS0DxSw Funnily this will be the highest resolution MFT camera ever then (32mp) RE: 8K MFT camera by ... Sharp! - you2 - 01-09-2019 For those who don't watch the details - no details - full details at NAB q2 of this year. I guess the sensor would have to be around 36MP to support 8k but maybe they are interleaving images or something to keep the density lower ? RE: 8K MFT camera by ... Sharp! - Brightcolours - 01-10-2019 32? 36?? 8k is 7680 horizontal and 4320 vertical. 7680 / 4 = 1920. 1920 * 3 = 5760. 7680 * 5760 = 44.2Mp. RE: 8K MFT camera by ...

That's 33.2 Mpix, or if you define it old school. 31.6 Mpix (generally rounded to 32 Mpix). Kind regards, Wim RE: 8K MFT camera by ...

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. RE: 8K MFT camera by ... Sharp! - wim - 01-10-2019 (01-10-2019, 05:30 PM)Brightcolours Wrote: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.(01-10-2019, 04:33 PM)wim Wrote:Uhmm, no.

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 RE: 8K MFT camera by ...

What makes MFT is the 4x3 aspect ratio. What is the diamater of a rectangle? RE: 8K MFT camera by ... Sharp! - Klaus - 01-12-2019 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). https://www.blackmagicdesign.com/au/products/blackmagicpocketcinemacamera/techspecs/W-CIN-12 RE: 8K MFT camera by ...
