I decide based on camera AE mode I select. I have already done it in U2 mode where the camera is set to TAv, with 1/10th shutter speed by default. My only complain is when ISO goes down to ISO100 and blink (over exposure), the camera is not able to correct settings to expose correctly, even if Auto-exp. compensation is enabled. It's easy, every time I know that the picture doesn't contain motion, I want to use the slowest possible shutter speed and lowest possible ISO to get the best image possible. Using TAv works for me, except that I have to manually adjust most of the time because there is nothing in the AE program to do what I want automatically. And as others have said, there is already an ISO speed setting (Slow, Typ, and Fast) so why not extend this to Extra-slow (3 stops), Very-Slow (2 stops), Slow (1 stop), Typ, Fast (1 stop) , Very-Fast (2 stops), (3 stops) Xtra-Fast. I don't understand why people are opposed to improvements.
