You could also try using Av mode. On my K-50, the camera still stops down the aperture as defined by the ring. Since the camera doesn't actually know that aperture, you need to get it to provide the correct exposure, and you can do that by using exposure compensation. If you're shooting wide open, then exposure is correct without compensation. Otherwise use the appropriate compensation.

Seems to be a much more accurate method for getting the correct exposure than using the green button in M mode. Also, can make shooting off several frames a lot quicker.

The camera is pretty-much always et on AV mode and was when I was getting odd exposures using just the shutter button rather than the green button.  As I mentioned in another comment, I'll experiment further but from limited testing today the green button seems to work better - and frankly, I can't understand why it should!
