When not using SR there is no way to allow the camera to know what manual lenses is attached to the camera. It should be possible to always be able to dial in what lenses is attached to the camera? Seems like a simple task.

If the lens doesn't automatically relay this information, you can manually input the focal length. This is for Shake Reduction only, and every SR capable camera has had this functionality.

What I was getting at is that when SR is turned off for manual lenses there is no way to input what lens is attached. It would be nice to be able to input the exact lens attached for future exif data reference regardless if SR is on or not. Would also be nice if we could dial the aperture being used on any particular M, K or Tak screwmount lens too.
I see this really going one step further as well. If Pentax allowed the input of exact A, M and K series lenses including Taks this data could be used to expand the lens correction features implemented in the K-7 to all Pentax lenses.
Due love the backward compatibility for certain. One reason I am a Pentax shooter.

Of course, one is only interested in selecting the lenses one owns or will use with a particular camera body.
I suggest this might be done as some kind of ROM database where a group of lenses (User Lens Database) is selected on the computer, in software or by hard connection to the camera, from an exhaustive list (perhaps limited to Pentax manual lenses) and/or by freeform entry by the user.
If direct connection to the camera is not possible, then the User Lens Database might be transferred to the camera via an SD card, such as doing a Firmware upgrade.
User could then select a manual lens from a pick-list in one of the camera menus. Data might include lens maker/name, focal length and min/max aperture, the latter two having utility for camera functions.
Aperture in use could be picked up from e-dial (of course, the user would need to set the lens aperture and the e-dial, and they would have to agree).
Of course, that's a tall order for the engineers, but it would certainly set the next Pentax body apart from the competition.
