Having bought second-hand about a year ago a Pentax Power Zoom 100-300mm lens, I have followed this discussion with interest. I have both a Pentax K-5 and K-5 IIs. I have downloaded the manual from Pentax and tried some of the pages with limited success. I have thed the P and A positions and they work. I am unsure of the AS position and the button. I get nothing on the screen on using these and the button. The button I have has a small knob on it which allows it to be rotated. Do you know anything more about this feature?<br>
