Hey everyone,
I have read in more than one place that most lenses are sharpest at 2 stops from full open. My question is, what is 2 stops? Is it the difference between F1.8 and F4? Or is it 2 changes in Fstop from full open? For example, If I was using F1.8, and used the dial on my canon to close the iris down and it clicks 2 times.
Thanks
Matt
