If I want to force use of the built in flash ( to fill in dim subject against bright background ) I can use P mode and it will use a shutter speed between 60th and 200th to ensure the flash fires.
That works great outdoors in daylight.
However in a dim environment, in P mode with the built in flash popped up, it uses f7.1 or f8 and cranks up the ISO really high, say, 4000. (Without the flash, it shoots wide open and ISO above base but as low as it can get away with, say, 1250.) Why doesn't it open the lens as wide as possible and keep the ISO as low as possible with tree built in flash?
