Item Description
This is an M42 Screwmount to Pentax K Mount adapter.

It is not the Pentax Brand adapter. But it does work well, and allows focus to infinity. It seems very much like the Pentax brand in design.

It is a Rokunar P-K Body Mount (For Pentax K to Pentax Screw). it was made by a company called Aetna Optix, which had several names it sold camera gear under. Aetna - Camerapedia Based on the packaging I'd estimate this was an early 1980s product.

It has the clip like the Pentax brand adapter that holds it in place. I normally used my fingernail to press that and get the adapter off the body. Once I had to get a small flat head screwdriver to get it off. My fingernails were too short. You can see a few scratches where this has been done by previous owners as well. You can see the clip in the pictures. To be safe, I'd suggest packing a small screwdriver just in case.

The adapter does what it's supposed to, it allows you to mount M42 lenses to K Mount bodies. It's in generally good shape.

The price includes Paypal fees and shipping via 1st Class Mail to the USA.

Plus, I'll throw in a set of cheap K mount extension tubes. Nothing special, but they work enough to let you figure out if macro photography is for you.

So you get the adapter, box, and cheap off brand extension tubes.

Are you the original owner of the item being sold?
