Autoexposure means the camera will AUTOMATICALLY adjust at least one variable ( either shutter speed, aperture, or in the case of digital, sensitivity(ISO) ) continously as the lighting/subject intensity changes. None of the Pentax DSLRS can do autoexposure with K/M lenses. The green button routine is a one-shot metered manual with an "automatic" shutter speed setting done for you but camera doesn't continously readjust as light changes from shot to shot or if aperture or ISO changes so it not Autoexposure with green button routine. Its much more like an easy one shot metered manual which is not the same thing at all.....

It's true you must press the green button your self. But the camera still chooses the shutter speed it self, when I set the aperture. To me that?s still Aperture Priority Auto Exposure. I don't have to make adjustments or even notice which speed is chosen.

Hello Jens, Sorry, I do that all the time. I call that manual mode. If it were true aperture priority, then as the lighting changed, so would the shutter speed without me doing anything. The shutter speed does not change until I press the green button again. It doesn't bother me, but for someone else, who is really wanted aperture priority, it could. Just telling it like it is. -- Best regards, Bruce Wednesday, August 3, 2005, 9:41:19 PM, you wrote: JB> Set the aperture to what you want.
