KF06.466 is an automatic adapter,achieving autofocus, aperture control, EXIF ​​information transmission, lens anti-shake and other functions. 

This adapter is non-electronic and so will not enable electronic communication between lens and camera, so no autofocus. 

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series（aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

 

I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure. 

yeah, this is just a basic adapter... you need to get a metabones adapter if you want the lens to "talk" to the camera ($650).... that's the whole point of the metabones
