A few questions, and some background for each.
I was thinking about this when replying to another topic, about how the 6K model has Native ISOs of 800 and 5000, while the the 8K model has Native ISOs of 800 and 4000.
1) Does this mean the 8K model is noisier in low-light situations than the 6K?
It's my understanding that a Native ISO is the voltage to the sensor that produces the lowest amount of noise.
So that also leads me into my next question:
2) Where on its ISO scale does the Ronin 4D 6K sensor switch from the voltage of 800 ISO to the voltage of 5000 ISO?
200 250 320 400 500 640 *800* 1000 1250 1600 2000 3200 4000 *5000* 6400 10000 12800
Another way of asking this question: Is 1000 ISO just 5000 ISO with the gain turned way down (applying negative gain to the signal)? Or is 1000 ISO the voltage of 800 ISO with gain applied?
If it's the latter, then I'd assume the Ronin 4D-6K uses the voltage for 800 ISO all the way up to 1600 ISO, and then switches to the voltage for 5000 ISO at 2000 ISO. But there is no evidence to this assumption, hence why I'm asking. I'd like to know for sure what DJI says.
Which leads me to my final question, which I believe other users here could answer as well:
3) In terms of noise reduction, is there any point to shooting at ISOs lower than 800?
Let's assume I can completely control the lighting on my set. So that if I want to shoot at 200 ISO instead of 800, I can always use brighter lights (even if I want to stop down or shoot at a higher shutter speed). Why would I bother? Will I see any real reduction in noise?
Thanks everyone, hope you're all having a wonderful week!
