I noticed that if I set to ISO Auto and shoot in one of those 3 modes, all the photos came out with ISO 64.
So I did an experiement. With the Lens cap closed, flash off. I shot in S and M mode with a fast shutter speed. The images came out black as expected but ISO was always at 64 when I reviewed the images. 'A' mode was hard to test as the camera would simply have slowed down the shutter speed to compensate.
I thought with Auto ISO and the manual settings, if the exposure was still not correct the camera should have adjusted to a higher ISO value. Is this how the camera is supposed to function? or is there a defective firmware. The manual does not state that ISO will be fixed at 64 if in Auto ISO for the manual modes.
