Originally posted by johnny9fingers So you set the camera in Manual mode and press the green button, which tells you what the camera thinks are the best setting for exposure. Then using that as a guide, (with the lens set at M) set the aperture & shutter speed for what you wish to achieve. The switch the lens to A, (if needed due to how much light you are working with), focus, switch the lens back to M and fire....?
In M mode, the Green button locks in the shutter speed based on your manually selected aperture and IS0. I think on the K20, you have to set the Green button to Tv shift, but I'm not sure. (On the K-x, the ev+- button does the same thing.)
But you always keep the lens on M--never A.
