I normally don't use ISO Auto, but wondered how it would work with the D2x. I set it to ISO Auto in the menu and it shows Auto on the rear display with "100" below it. However, every photo I've shot has been at 100 on Auto even in lower light, it shoots at 100. Most were 1/60th at F4 using a flash and even without a flash, it stuck to ISO 100. I read the manual and it said that when set to Auto, the camera will increase ISO when needed. Does this mean that all the low light shots I took last night without flash were accomplished at ISO 100 or am I missing some other setting?
