M42-Mount Lens to Pentax K Camera    Anodized-Aluminum Construction

If your M42-mount lens has no aperture pin, tabs, or levers; or if it has an aperture pin that does not fully depress (small tabs stick out), it is considered a type-1 lens and this V1 lens mount adapter is compatible with it.

However, if the aperture pin of your M42-mount lens depresses all the way down, your lens is considered type 2 and is compatible with V2 adapters (available separately).
