I just picked up a refurbished D60 and I'm experiencing some strange things with ISO in Auto mode. I just shot pictures of my daughter's birthday with the camera in AUTO and using a SB-600 on camera. I was bouncing the flash off the ceiling. All exposures looked good, however, ISO was all over the place (200-1100). I have no idea why the camera would select 1100 ISO when using flash. Any thoughts?
