With the m42 lenses the entry screen for focal length comes up automatically when you turn on the camera after mounting the lens - apparently the K10D also senses lack of any connection - this is with the Pentax M42 adaptor - NOT the wide flanged one that mucks up the infinity setting.
The camera also verifies focus and gives the suggested exposure for the aperture as set on the lens - M setting enables adjustment of the exposure as needed With the M lens the aperture is NOT communicated to the camera but in M mode you can determine the exposure at any selected aperture by using the green button as the stop down on exposure still works - this was the only way I have found to access the metering :) With the M lens you also need to set the focus to Manual as the other modes lock unless focus confirmation is triggered - useless at infinity focus when the focus point is on a featureless sky. This was not needed with the M42 lens. The lock unless focus confirmed is handy for quick and dirty Macro images - just hold the button down and slowly move to get focus and the camera will fire when focus is confirmed :) Both lens types require that 'Using Aperture Ring' in screen 6/6 of the 'Custom Settings' menu is set to 'permitted'.

But A and older lenses require you to enter the focal length (With K mount lenses the selection screen comes up automatically, but you need to menu-dive for M42 lenses as they won't cover the contacts and thus indicate their existence to the body). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
