I've recently made tests between 3 different camera. RED EPICX - Canon C500 + Odyssey 7Q - Sony FS 700 + Odyssey 7Q.
The little Sony FS 700 was nearly as sensitive as the Canon C500! But the minimum 2000 ISO given for the RAW recording had quiet the same level of noise as the C500 at ISO 850.
Of course the noise of the C500 looked more organic! But come on. The Sony FS 700 was even better than the RED EPIC X regarding there respective sensitivity!
So, FS700 + Odyssey 7Q is quit a good raw recording option but still limited by sony to 2K RAW 200fps.
4K RAW 50 fps is still only available with the AXS R5 from Sony. But this is a real Bazooka with an hawfull ergonomy.
So, Please sony give Convergent design the ability to record 4K RAW 50fps. They are just waiting for your go.
And sony's bazooka doesn't fit my underwater housing!!!! It restrict 4K raw recording to underwater studio.
Odyssey 7Q could do the job and does fit my housing!
