Hi All, I have my D200 set up with the "Nikonians" recommended custom banks. In Bank "D" the "Action" settings recommend auto ISO. Today I was shooting motorcycles in bright Southern California sunshine. I was in Manual mode at 1/500 SS and f11. The ISO was set to auto. Now I'm looking at my shots in Lightroom and I see that the auto chose 800 ISO and the pics are very grainy. Does anyone have any idea why auto would select 800 in bright sunlight? I metered off the sky and the cmaera showed 1/500 at f11 as a correct exposure... Any thoughts would be apreciated.
