Where can I buy a converter from the old Pentax threaded lenses to the bayonet mount so I try some of my dad's old Pentax lenses on my K10D?

Have you tried eBay? I would assume that you meant the M42 mount. If so, I would suggest you to ask the seller about the infinity focus capability before getting one. I bought quite a few, and only the official one can yield infinity focus. I heard that the Bower one can also do the same thing.

Does Pentax offer one? That is what I would be looking for if they did.

I believe thy still have one in the line and if you are near Robinsons Camera, they can order one for you. Ebay is also a good inexpensive source for these. Just make sure you don't get this version: https://www.pentaxforums.com/forums/attachments/pentax-camera-accessories/654...-k-mount-1.jpg

Here is the 'direct from Pentax' source...

PentaxWebstore - Photo Imaging

Look under 'SLR Lenses', third page...

Unfortunately, they always seem to be out of stock.

I can confirm the Bower adapter allows focus to infinity.

MORE HELP. Ihave a spare Genuine Pentax adapter.

tybeck · 01-27-2008, 07:51 PM

I've heard good things about the Roxsen adapters on eBay. Ended up ordering one up since the M42 adapter I have now won't let me go to infinity. Can let you know if it works once it comes in.

aegisphan · 01-27-2008, 08:44 PM

I do have one Roxsen one. It wouldn't give the IF. To be honest, just get the genuine one to save you money and time later.

Henrys Canada Sells the pentax ones for $25CAD.

Thanks

PS. Its been out of stock for awhile now so wouldn't count on them, but you could give them a call and ask about.

......there are a few up on eBay right now. Currently they seem to be going for between $35 and $50. One is there with a $40 BIN and free shipping.............I have six.Is that too many?

I got tired of waiting on the Pentax store. Ordered this General Brand | Pentax-K Body to Universal Lens Adapter | B&H

It is listed as "General" but when it came it was a "Bower" Looks exactly like the one in the Pentax web store right down to the red dot. About $20.00 with shipping. Don't know about Canada.

Porter's has the genuine Pentax m42 adapter...
Pentax Mount Adapter B: Porter's Camera Store: digital cameras, film camera and photography accessories
I ordered one on Friday and I should be getting it on Wednesday, so unless I ordered the last one they had, they should have some in stock.

HTH,
Heather

Does anyone know if the Fujica M42 lens with the metering tab will work with these Pentax K adapters.

I could never get them to work on my Minolta unless I ground off the metering tab
