Help identifying lens mounts?

My Sister-in-Law just bought her first DSLR after pulling her ancient Ricoh film camera out of the closet and finding that it no longer worked. Anyway, she picked up a Canon XSI (450D) and wants me to help her get rid of her film lenses in order to fund a cheap Canon 50mm f/1.8 or something equivalent.

She insisted that these were Canon FD lenses but several forums are telling me that they are likely K-Mount. I thought I'd ask here to see if I can get a positive answer:

Ricoh Rikenon P 50mm f/2
Front:
Rear: http://goo.gl/PHIY
Profile: http://goo.gl/4USU

Sanwa 35-200mm f/3.8-5.3
Front:
Rear: http://goo.gl/ImmX
Profile1: http://goo.gl/a2TS
Profile2: http://goo.gl/nIeG

Kenko FD 2X Teleconverter
Profile:
Front: http://goo.gl/DFnF
Rear: http://goo.gl/suJz

Ricoh XR Speedlite 300P (Stand not included)
Front:
Rear: http://goo.gl/8Cce

Any help identifying these would be greatly appreciated. Thanks!

Pentax K-mount (the clues in the KAX on the side of the teleconverter)

beware of the ricoh pin

Be very careful with all of these lenses. they are for a ricoh camera with program mode.

they have an extra pin, visible in the rear photo, a little further clockwise around from the normal pentax aperture coding contacts, which is a smaller diameter than the pentax pins and has the tendancy of getting locked in the AF drive on the pentax camera body.

The lenses will otherwise work, but there are horror stories about these lenses getting stuck on the body.

it is best to remove the rear mount and this pin, or otherwise remove the pin before youever mount these to your pentax camera.

otherwise, they will work.

Sounds good then. Thanks for confirming!
Any idea what they'd be worth? I'll likely be selling them for her rather than trying to find the right adapters.

there is no issue of adaptors, just remove the one pin from the mount then they are useable on pentax safely

as for price

the 50mm F2 is worth $20-30, the zoom perhaps $35-50 and the TC perhaps $35 in my opinion

These are not FD lenses. They are K Mount (perhaps labeled as KR "K Ricoh.")

It is very, very easy to cleanly remove the pin; no need to grind or cut. See the following link:

theatre of noise: Ricoh Lenses On Pentax Cameras -- The Ricoh Pin Fix

(I would save the pin in case you ever run across a Ricoh camera to use it on.) The prices that others have quoted seem about right.

She has a Canon body so I'd have to find a K-to-EF adapter; likely one for each lens for convenience's sake.

I think I'll just post it for sale as a bundle for ~$80 (if that sounds reasonable) and let the buyer do the pin removal themselves!

Now to read the rules on the for-sale section... Thanks for your help everyone!

Are you sure the camera is toast? The kit as it exists would make a nice film setup for anyone wanting to use it if the camera were working.
