pentax 300mm f-4

I am thinking of buying the new pentax 300mm f-4 lens . But i want a tc for it at 1.4. Can some one tell me one that will work and where to buy it.
I have seen the reviews and think it is a good lens for nature.
Am currently in Thailand and want it for bird and wildlife pics.

Hi Gary - welcome to the forum.

I am guessing ypu have the DA* 300 - top lens.

I have the Tamron 1.4 SDM TC and can tell you it is virtually useless with the 300. You will get a better picture with a crop without the TC. I believe the Pentax AF TC may be better.
