Yes. They work in auto exposure with manual focus.

Yes. As per photo.net, "A" designates a line of old manual focus lenses so you must use Manual mode on your K200D. A good tutorial is at: dpreview

"A" designates auto aperture, so it's not completely manual. You can set the aperture from the camera Av setting.

If it doesn't have anything other than "SMC" (or nothing at all) then it's a completely manual lens. You'll need to enable the use of the aperture ring in the custom settings of the camera, or the camera won't release the shutter.

Sorry to interrupt here, but I guess there might be a little misunderstanding.

With K mount lenses, just check if the lens has an "A" setting in the aperture ring. If it does, then set the lens to "A" and use as normal AF lens, but with manual focus. You can use every single exposure mode available in camera. (Program, Av, Tv, Manual, etc).

If the lens does not have an "A" setting in the aperture ring, then you have to set custom function in camera to "allow use of aperture ring". In this case, exposure mode will only be MANUAL. No auto exposure modes will be available. But remember the little magic green button in ALL Pentax bodies. Just pick your aperture, press green button and you are in business!

Try to do that C and N, with 30 yrs old lenses. Bet you could not even mount them!
