try to keep the ISO in multiples of 160 i.e. 160, 320, 640, instead of 100, 200, 400, 800

Interesting, why?

I can't find the link, the site or even the original post right now (grrr...) but there was a test by a bloke that showed distinct dips (and I mean they were really obvious) in the noise coming off the MkIII sensor at ISOs that were multiples of 160, as if that was the true base and IIRC the intermediate values required an additional "pull-up" amp stage that introduced extra noise. It still didn't get down to D800 levels but it was definitely an improvement over the standard vales (100, 200, 400, etc.).


cool, I'd like to see that test.
