nice GH2 ISO test

Interesting ISO test:

Looks like better ISO at 320, 800, 1600 and 3200
Strangely, ISO 2500 has more noise than ISO 3200
The intermediate settings shows more noise or is it my impression ?

Sage, a member of this forum, conducted these tests

Here's the thread:

I cant wait for more extensive testing of the ISOs.

I have read that the ISOs to avoid at all costs are the multiples of 125. -- so 250, 500, 1250 should be avoided because they add digital gain and therefore noise. Not sure if this is true or not and haven't bothered to test, but have tended to avoid these anyway. And this formula would, of course, include ISO 2500.

200, 400, 800, 1600, 3200 look nice....would avoid others, except 320. Great test.
