Hi Stefan, thank you very much for your help. Yes it is the one in your picture. I tried it today in seriously bright sunlight and absolutely nothing happened.

The one on the photo is the MC not the needed SHQ
It's very strange since you have the contacts needed, maybe they aren't connected correctly.

Might be worth screwing one open since most new lenses will be SDM only.

Very good but very expensive the Pentax 1.7
It has his own focus part so every lenses even old manual ones have auto focus.

The Pentax 1.7 adapter is my preference!.....gives you 510mm 6.7...and there is no noticable difference in image quality.....and you can still find them out there.....Ken
Yup - next to the hen's teeth.

Thanks Barry - I did see that one, but I am a little nervous about buying from China on Ebay. I would want to check they spelt "Pentax" right first.

I've had one from them BNIB shipped from Japan all spelling correct, soft case and all. Tested on DA*300 works fine.

If you don't mind me asking, how much did it cost?

My Tamron 1.4x MC4 works fine with the 16-50mm and 60-250mm using SDM.
The 1.7x also works but of course you lose SDM and you have to manually focus close to the target before it will actually lock on using its own focus.

Thanks everyone for your input, didn`t realise they were quite so pricey but then it`s world class kit. Might try the 1.5 kenko from SRS, looking at their image it seems to have the right lettering on the barrel.

I seem to remember someone on the forum trying one of the Kenko 1.5x from SRS and it didnt work with the SDM lenses.
Best ask Chris to try one first.

Stefan, I have just tested the continuity of the contacts on the 2 X TC. Not all have continuous connections and one connects to two contacts.
