Reduce Noise 7D and 5D Mark II

In a discussion forum on another website concerning reducing 7D noise, the suggestion
was made to use non-native ISO in multiples of 160.

As to be expected there were many opinions. However one contributor did some extensive tests to show the value of above.

Here are his discussions and test results. It does make for interesting reading.

Garry - interesting article. thanks for posting it.

I just read through it myself and it's definitely an interesting read. I don't really see a huge difference in noise at lower ISO and I usually don't use an NR on shots until ISO 800+. There's a ton of nerd talk and graphs which are way over my head but the first graph pretty much sums it up. I use ISO 50 when shooting outdoors with my strobes but I might rethink that since I'm losing DR and highlights
