1 stop instead of standard 1/3rd.
Mar 9, 2011

I can set increments to 1 stop instead of standard 1/3rd via C.Fn I - 2.
I am using 1/3rd since i have my 7D.

1 stop represent the true existing ISO (100-200-400 etc) and the 1/3rd are derived from these.

They say that true ISO will have more noise but also more dynamic range. On the other side, 1/3rd increments will have less noise but also less dynamic range.

Will i really see a difference switching to 1 stop? Is it a real downside of true ISO?
