It is for changing the aperture on cameras which do not have the ability to do so from the camera body, like older film cameras (ME Super, MX, LX etc etc). On your K10D you do not need it, just leave it set to A and change it from the camera body.

You would do well to read a couple of introduction to photography type books, there are lots out there.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.
