It would make sense as it seems "most" micro 4/3 sensors have a base ISO of 200. But besides that, I have read up that for high end cameras (BMPCC, RED, ARRI, ect..) there is a sweet spot for the most dynamic range (not necessarily least noisy). Some cameras have the same dynamic range no matter the ISO, while others change dramatically. For example, on the BMPCC forums, its said the base iso is 800, and to try and stay there to get the most dynamic range out of the super 16 sensor.
The X5R is advertised as 12.8 stops of dynamic range, is that at ISO 100 or 200... how about 800... or every ISO? For all we know, at ISO 100.. may not even break 10 stops. we may need to be in the 400+ territory before we get close to the advertised 12.8.
So... this is the type of information I am seeking. Im sure other X5/ X5R owners would like to know this as well?
Read the info here on ISO / DR: http://www.gunleik.com/tests/ale ... n_introduction.html
ill put up more examples as I come across them. |
