Best ISO values on the FS 100?

I suppose a quick test with the lens cap on should do the trick ;) If and how PP would affect the results.
Will do a test and share the results here later.
 
A test would be interesting but in my experience there's no 'native' ISO issue like with a Canon DSLR. This is a real camera. :-) And let's face it, even on a DSLR bad exposure trying to stick to a native ISO will kill your image way more than dealing with a bit of extra sensor noise.
 
when the fs100 was first introduced, i believe andy/abel cine/nyc "rated" the iso of the s35 chip in the fs100 as 500asa.

ymmv

be well.

I've just done some tests on each iso value and how they match to each other.
As you guessed, i could find nothing like "native iso" .

Each iso value increment adds a gradual amount of noise until you reach 10000.
(12800 and 16000 aren't really usable)
 
Every digital sensor has s.th. that we can call native ISO or base ISO. It's 500ISO with hte FS100. If you go up from here, noise will increase.

Is it a problem: No. Because the noise floor with the FS100 is very low.

I use the FS100 without any flaws up to 1600ISO and add 3200ISO when really needed.
But when you check your exposure, learn to use the histogramm! The display is really a mess, it shows black parts all over your picture, where your footage is still fine.
I tend to underexpose the FS100 when looking through the display - but use s.th. like ETTR without clipping.

Don't forget to use the picture profiles, as the FS100 is 8bit only - every look will more or less be baked in!
 
Yes, the native ISO for the FS100 is 500. +3db gain = 800 ISO, +6db = 1000 ISO, +9db = 1600 ISO
The FS100s 35mm sensor doesn't hide the grain/noise as well compared to the 5D, as it's only about half the size of the 5D sensor.
 
Instinctive reply, without checking exact figures; the 5D sensor is bigger, but it must have a higher pixel density, and therefore, theoretically, more prone to noise...
