Converter

Hello.
As is the new Pentax will launch the new converter 1x4.
But I have a Sigma 70-200mm f2, 8 OS HSM, and i want to convert 2x to use this lens.
Does anyone here knows if the Sigma will release the latest version of the 2x converter for Pentax?

Best Regards for every one

I read somewhere that Sigma no longer make their converters for Pentax and there is just old stock in the shops now. It's a shame they didn't update them for HSM as I have the 70-200mm and 2x in Canon mount and they perform pretty well together.

Shameful typo corrected

The latest Sigma 70-200EX OS HSM works very well with the Tamron 1.4x PZ AF MC4 converter.....

But not in the subject line.

Although I suppose a 1.4x and a long lens might be used for covert work.

Title sorted.
