I'm moving to all K-mount lenses, so I won't need this adapter anymore. It is a genuine Asahi Pentax M42 (screwmount) adapter that allows infinity focus, unlike most of the adapters out there. Also, you don't need a special tool to install or remove it like you do with some adapters -- a quick flick of a fingernail will do it. Very quick to install and remove. $50 shipped.
I also have one of the cheaper adapters for sale that doesn't allow infinity focus. I keep it attached to a Super-Takumar 50/1.4, which makes an incredible portrait lens (infinity not being that important). $10 shipped.
Or I'll sell both for $55 shipped. I prefer Paypal for this sale.
