Tamron SP 500mm on K10D

I was wondering if anyone has used a Tamron SP 500mm (the mirrored one) lens with the K10D with any success. I can use my other SP lenses if the lens has the AE option on the f stop ring.

If anybody has discovered a method to make this lens work, please let me know.

Well yes, I've made it work quite well.
You have to use the green button kludge, IIRC.
Set camera to allow shutter release with lens off the A position, set camera to manual exposure and press the green button to set the shutter speed.
Adjust shutter speed or ISO as required to get the correct exposure.

I am trying to use those settings, and as far as I can tell, I'm doing something wrong.

1) Ive got the body on 'M' mode.
2) The upped LCD screen is displaying a flashing 'F--', and nothing seems to change this.
3) Green button 'kludge?' Is this a typo?

manual aperture lenses will show f--- because you use the aperture ring to change f-stops. A mirror lens has no aperture blades so you shoot wide open and should be able to use green button in m mode to set shutter speed but you program camera for tv shift when using green button in custom menu. I think A mode should work if you want auto shutter speed selection.
hope this helps

Thanks for the help. I can't find anything in the manual for "tv shift". Could you please advise where this is located?

Thanks for the help. Funny enough, the problem turned out to be my adapt-all. As soon as I removed it, the lens worked fine in manual mode.
