It really is best on a pancake camera to shim the back so that all lenses focus beyond infinity. A hard stop infinity focus with a helical is something that can vary with temperature swings. If you happen to own any lens that has an infinity stop that cannot be adjusted on the lens( such as the Schneider 150mm ) then shim that lens to go beyond infinity and hopefully all other lenses will also focus beyond infinity. If not then adjust those lens rings.
