K-7: no SR for manual lens?

On the K20D, with SR switch on, using a manual lens (e.g. 800mm f8 mirror), user is asked to input focal length - can have SR on, enter 800mm.

On the K-7 (SR switch in menus), menu 4 Shake Reduction (on/off) and Input Focal Length items are disabled, so no apparent means of enabling SR, setting focal length. Seems wrong. Wondering if I'm missing some related menu item that needs to be turned on to enable SR in this context.

from p. 134 of the manual:

SR is automatically turned off in the following conditions:

---self-timer mode
---remote control shooting
---bulb shooting
---HDR capture
---mirror-lock-up shooting
---wireless mode w/ an external flash

Are you using any of the above?

Even though your lens has a fixed aperture, you may need to go to the C Custom Setting 6 menu and set "Using Aperture Ring" to "Permitted" before it will allow you to turn on SR. (See page 294 in the manual). The camera requires that to be set to "permitted" for any lens that does not have an A (automatic) setting on the lens, which presumably your f8 mirror lens does not.
