Vivitar PK-AR Lens: Dangerous to use on my K-x?

Hello everyone,

The delay of the delivery of my K-x might be a blessing in disguise, for it seems to me that I would have had to have shelled out a huge amount of money to get it repaired had it gotten stuck because of a Ricoh pin.

Here are some pictures of the lens. Tell me what you think.

Thanks,

TexasLangGenius

This sure looks like the sticky version of the Ricoh pin: pointed and protruding enough to catch in the AF drive slot.

Yes. I'd try to carefully remove the screws securing the silver colored bayonet base, remove the base, remove the offending pin, and replace the bayonet base.

PS maybe you can glue it down or cut it off with a Dremel tool, but I'd try the above first.

Yes, that is the dangerous version of the pin. You are lucky to have spotted it in time! Removal should be pretty straightforward. Good luck!

Here are some higher resolution shots of the mount.

So the one on the left (the big, pointy one) is the Ricoh pin, right? I suppose the other one is the Pentax contact, so I can leave that one in. I just want to be sure.

Yes. The pointy one on the left is the Ricoh pin. Be sure to keep the other so that auto modes work.

Offending pin removed. It took me only three minutes to do it, too.

All I did was take my miniature screwdriver, undo the screws on the mount, and lift up a tiny metal plate. It was so easy.

I removed the screws on the outer silver rim, not the ones in the inner black rim.
