Sam Using a K or M lens on the *ist D is not that cumbersome - provided you are using Firmware 1.1 or 1.11. Pressing the green button takes just a fraction of a second. The *ist D will stop down and measure the light comming through the lens, stopped down to working aperture - and the camera will remember the metered value until you fire the shutter - or at least long enough to make a decent exposure. It's just as fast as focusing with AF, i.e. Of cource it's not as fast a using an A, F, FA, FAJ or DA lens. And you still have to remember to press the greene button everytime the light/FOV changes.

Shel, it is metering combined with some mathmatics. To truly meter the light the lens would have to be stopped down to the aperture you want to take the frame with. Since this is cumbersome (try using a K lens at the *istD) it is metered with open lens and the difference is calculated somehow. If the data about how the lenses stopping down influences light metering is somehow incorrect there will be a wrong result from the calculation and the pictures would get too dark or over exposed.
