Why does P shift only work with auto ISO in one direction?
On my K-x, I sometimes use program line shift in P mode. I can use the wheel to shift towards smaller apertures in one direction and towards faster shutter speeds in the opposite direction.
When I shift towards smaller apertures (higher f number), the camera will increase the ISO if necessary to give me the really small apertures.
But when I shift towards the faster shutter speeds, the camera won't increase the ISO when it bottoms out on wide open aperture.
Odd. Can anyone explain why?
Sincerely,
--Anders.
