Pentax-A 50mm f1.4 problem

I have just received this lens and love it so far - the smooth manual focusing and speed is a dream! Anyhow, I'm having one issue - I have the aperture ring set to "A" and am using the camera in manual ("M") mode. However, every time I take a photo the shutter speed and aperture seem to change. I can't see any logic to it. If I set the aperture on the lens ring, the shutter speed still changes itself each time I press the shutter release, though of course the aperture stays the same in this scenario. Could anyone provide any suggestions?

Do you have Auto Bracketing activated?

Sounds to me like you have Bracketing on as well.
