- Bruce, these are all the older models, not the new models from Kenko and Tamron that Jens referred us to with this link: http://www.nikonlinks.com/articles_teleconverter_review.htm#Overall%20results These new ones don't seem to be available yet (ever?) in Pentax autofocus mount, except that Adorama has the Tamron 1.4x version. At $550 the A 2.0x L is just too expensive for a TC. Joe
