Hi Juan, Thanks for jumping in. As I may have said, ISO was the same in both instances - 200. No automatic ISO. EXIF data shows ISO and Exposure to be the same. I double checked the lens aperture several times - it didn't change or move Here are the URL's to the pix. Maybe there's something I'm missing.
