At the photo club I attend. I had a gentleman tell me that ISO 200 is a better setting to be using on the D80 than ISO 100. I haven't found any indication of this on the internet, with the exception of less highlight clipping at ISO 200 for the Nikon D300, however this camera uses a different processor. I've checked dpreview, fred mirada and bythom and I still can't find any indication of this. It just doesn't make sense to me. Can anyone shed light on this?
