Re: non A lenses on the istD

[Paul Stenquist]

To expand on this answer, the camera should be set to "M" on the 
exposure method dial. With your image framed, push the green button, 
and the camera will set an exposure based on center weighted metering. 
Of course you must have firmware version 1.1, and you must set the 
custom functions to allow firing of the shutter when the aperture is 
not set to "A."

Amita,
Two things - you have to have the updated firmware loaded onto your
camera (you can get this at the pentax website) and you have to set a
custom function to allow firing of the shutter when not on 'A' setting
