It works even with handmade pinhole lenses.
Could be a little tricky for inexperienced users with old manual ZOOM lenses.
When you turn on your camera it will ask you for FIXED focal length which is related to amount of sensor stabilization movement.
If you change focal length on your manual zoom, camera couldn't detect that and stabilization will stay on initial focal length.
You can fix that (without turning your camera off and on) by entering menu and changing menu option for that purpose.
That could be annoying for some users and in good light conditions they usually decide to leave focal length on initial value which is usually: mostly used focal length on that particular zoom, lowest focal length or average focal length (probably worst option). It depends on their shooting style and light conditions.
SR is not working in video mode (last model with that option enabled was K-5), because of too much mechanical noise on internal microphone. Disabling that functionality is a pitty because external microphone always worked fine on my K-5. I think that should be enabled again but not as a default and with warning in user manual. I am 100% sure it could be done easily on K-1 with firmware update.
