Thank you for viewing. This is a mount adapter for using Pentax lenses on Sony camera bodies. It supports AF and aperture control, and is an excellent adapter that can also track in AF-C mode. The version has been updated to the latest Ver.05. Also, as internal reflections can be noticeable, "Fine Shut Extreme" (a light-absorbing material) has been applied to the inside. (The photo quality will be better with it attached, but please remove it if you are concerned) [Product Contents] ・Main body ・Front and rear caps ・Instruction manual ・Original box
