Sorry! My question was not well written...and I've found the cause of the problem!
My K-30 was on M mode, using a DA 50mm lens. The ISO was not on auto. I'd adjust the speed and aperture to my liking and take a shot.
Problem - After taking the shot, I couldn't adjust the speed or aperture. I'd take another pic at the same "frozen" setting...and then be able to adjust the dials once more. So, ever second shot was adjustable!
Why? The Exposure Bracketing was on! (That's what I get for buying a reduced price demo model!)
So, all is good now!
Thanks guys!
