I've been owning a BMPCC for about half a year now. And been shooting with someone else's one for years.
It's still hard for me to understand the ISO Setting when shooting Prores in Film Log.
It's surely not your regular ISO switching process like on other Log cameras (e.g. FS 700 or C300).
If you only dial the ISO down from 800 to 200 (shutter and iris remain unchanged) the difference in exposure is not globally. The image seems to become more contrasty in the shadows. But you don't gain any highlight detail. Once blown out in ISO 800 setting it will also be blown out at ISO 200.
Anyways. My real point about this topic is this:
Lately I've been shooting with the Pocket using my light meter (Sekonic L308DC).
I always kept the ISO at 800. So I did some reading with the ligh meter and always ended up with an underexposure on the Pocket. After some messing around, I found out that the Pocket's real ISO sensitivtiy is ASA 100.
This applies when shooting in Prores and Film Mode.
However whenever I switched to Video Mode, my meter was right. Asa 800 in the meter was corresponding to ISO 800 in the camera.
Any thought's on that?
I find it really disillusioning to shoot with a camera that good but being limited to a native ISO of 100.
