Scarlet pro?

[Curran Giddens]

Canon did it in their concept camera.

I meant it would be a completely different sensor then what Red already has lined up.

I don't know where Red gets its sensors. Who knows what's available?

Pretty sure Red designs their own sensors.

 

[Stephen Strangways]

RED may spec what they want, but they don't have a fabrication plant so somebody else has to be producing them.

 

[Curran Giddens]

Right. I'm just saying I doubt they are off the shelf designs using someone else's tech.

Thanks David, are you sure?

Is the lens the limiting factor or is it the camera system? including OPLF etc etc.
My assumptions are based on 3.6(crop) of about 25Mpix (max) in FF yields about 7Mpix. (based on Canon still glass reference).
3K 2:1 would be around 4.5 Mpix ya?

But assuming you are right then,

- HDR is a go
- 3K is sufficient (but maybe more?)
- only sustained high speed and RAM buffered super burst remains a challenge.

Lens definitely. Find a lens that will resolve 4800 line pairs over the 24mm height of an FF35 sensor, 200+ line pairs per mm, and you will then have a lens that will resolve a 4k 2/3" sensor as long as your aperture is less than f2. Above f2 aperture diffraction will limit resolution. For 3k Scarlet diffraction limit is f2.8 and you need a 150 line pair per mm lens. So 3k is realistically about as high as is practical for 2/3" and you would be sacrificing sensitivity and dynamic range for higher resolution due to the smaller pixels.

In the last bit of specs listed the 2/3" could do sustained fps. 2/3" did 120fps in 3k and burst of 150fps.

It was the s35 that could only do 30fps with a burst of 72.

So using the as to now announced specs:
2/3" will have full module support, full wireless support, HDRx™, 120fps sustained, and so on.

So what exactly are you saying it's missing?

 

[JD Holloway]

@ David Rasberry - ahhh diffraction! Ya, thanks for that. I forgot about how that can rear its ugly head with smaller sensors. This board is a wealth of knowledge. Kudos.

@ JEC - I was not aware of this. Perhaps I was basing my assumptions on the s35 unit. 120 FPS is pretty damn good for 5 to 1 speed.

This will be a pretty great piece of kit...

Yeah, you can be bitten badly by diffraction. A friend shot with one of the first JVC HD-camcorders ( sensor was 1/3 ) and accidentially stopped it down to f16 in the Peruvian montains (yes, the Fujinon on that camera went that far).
The resulting image was resolving less than SD!
