I think we're talking about two different things. There's a custom setting that controls whether the digicam will allow lenses to be off the "A" setting. With this turned off, the camera will just display "F - - " in the LCD and refuse to work. Or to recognise that a lens is attached, if you like. This is the same for both *istD and K10D. I don't know for the other DSLRs, but I suspect they work the same way.
What I was thinking about, though, was what goes into the EXIF data of the image file. I interpreted Bob S. and Godfrey to mean that lens info for AF lenses was not written into EXIF with the lens off the "A" position, so I had to test for myself when I got home from work.
