The Kenko and Teleplus ones work as well, but I believe the Tamron is better.

The BBAR versions have better multi-coating than the non-BBAR ones, The MC4 indicates multi-coating and the # of elements, MC7 for the 2x. I just ran some limited tests with my 1.4x (non-BBAR) and by golly, it does focus the SMC lenses. But there is a loss of AF speed, probably due to the loss of light factor. And of course the screwdriver ones work as well. I originally got the set because they would work with my FA power zoom lenses, as well as my Tamron 300 ƒ2.8. originally On May 23, 2009, at 19:19 , Stan Halpin wrote: > I have a Tamron-F 2X Pz-AF BBAR MC7 > > Is that close enough? > > stan > > On May 23, 2009, at 5:43 AM, John Whittingham wrote: > >> Good price paid, cash waiting or may exchenge for Pentax related >> equipment. >> >> Regards, >> >> John >> -- Joseph McAllister pentax...@mac.com http://gallery.me.com/jomac http://web.me.com/jomac/show.me/Blog/Blog.html -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
