Description: Made of black anodized aluminium (camera body mount) and brass silver (lens mount) the KIWIFOTOS LMA-EOS_PQ lens mount adapter will allow you to use Canon EF lens on the new Pentax mirrorless interchangeable lens camera. The lens fits physically, auto-focusing control and camera modes which control exposure by automatically adjusting aperture are not retained, however. Preserve all focusing range up to the infinity point.
