>what do you mean old D7000 and new D7000 .......typo ???
No, is not. To make a long story short, I had a early D7000 and a recent D7000. They are both the same model camera, but one was manufactured near when it first came out. The recent one was bought at B&H, so I assume is recently manufactured.
The strange thing was they behaved differently in flash mode with auto ISO. I can actually set the ISO now whereas before I could not do it. Wish I still have the old one side by side to compare.
