So I have four lenses (three Vivitar one Soligor) with this type of lens system.



What is this called and is there a Pentax K adapter?

Vivitar TX, or TX 4 , I am sure available in PK. I had Nikon,Olympus OM , M42 , Minolta. I guess I still have Nikon and OM, common item seek ebay.

Why are these things always so expensive?!? Agh. At least I have two for Minolta to sell.

Is 17 USD is expensive to you ?

Seems cheap to me to use your lenses...

Sell your Minolta versions (now used by the M4/3 crowd) and spend the money on a PK Smile

Cheapest way to get these adapters is look for a lens that has the one you want. You can easily identify them because of the latch button.

Also, the PK mount is one of the hardest to find. They were made for the TX only, not the T4. (T4 and TX are mostly interchangable for our purposes)

Look for an M42 T4 lens. They are very common, particularly the 90-230 zoom.

I have owned just one T4 lens, a Vivitar-Tokina 28/2.8 with a bothersome aperture ring and a T4-M42 adapter. I bought it for US$14 and sold it for US$49. I guess someone *really* wanted that adapter!
