Adaptall teleconverter (mount) question...

I've never owned a Tamron adaptall lens before, but I have a 90mm SP f2.5 with PK mount on the way. That lens only reaches 1:2 without the Tamron teleconverter. But I'm not sure if I need to find a teleconverter with a PK mount, or if you remove the PK mount from the lens... attach the teleconverter...and put the PK mount on the teleconverter. In otherwords... with an Adaptall teleconverter do you actually need TWO PK adaptall mounts (one each for the lens and teleconverter) or just the one?

TIA for the enlightenment!

The SP adaptall converters go between the adaptall lens and your mount. There is also a tube that goes with these macro lenses that make them 1:1 without magnification.

There is an example at the bottom of this brochure.

Blue is correct. Remove Adaptall-2 PK mount from lens and attach it to the TC, then mount TC on lens.
