SImple question on Olympus Pen-1 auto ISO. What priority of shutter speed and F-stop does OlYmpus use when Auto ISO is selected. I changed Auto ISO to 200-3600. when I shot im Program mode the camera selected f14 at 1/5 second and iso 3600. Don't understand what I may have done wrong but I'd expect a balanced f-stop and shutter speed before it resorted to ISO 3600. Any ideas?
