Thanks, Don. Nice of you to let me know. I didn't know there was such a thing. I love the F 1.7 AF converter. At long distances, I can't focus this accurate manually. The AF converter simply gives me sharper photographs. Jens Bladt mailto:[EMAIL PROTECTED] http://hjem.get2net.dk/bladt
-----Oprindelig meddelelse----- Fra: Don Sanderson [mailto:[EMAIL PROTECTED] Sendt: 4. marts 2005 22:45 Til: pentax-discuss@pdml.net Emne: RE: AF teleconverters Hi Jens, the Pentax 1.7x is a unique tele-converter. It allows autofocus with manual focus lenses. The one Amita is referring to is a standard teleconverter that has a drive rod going thru to the lens. The lens still does the focusing, the converetr just magnifies.
