The only 28-80mm F2.8 lens of which I am aware is the Tokina ATX 280 AF Pro. Here's a link to the US distributor's spec sheet:
http://thkphoto.com/products/tokina/afl-04b.html A version of this lens is made for Pentax AF cameras. I believe that it is a pretty well-regarded lens. It is definitely not made by Pentax Corporation. The "USA and Switzerland only" description seems unlikely. Maybe it's just me, but I do not like it when sellers describe an item as a "Pentax lens" in the auction title and then described the item as "for Pentax, made by ...." in the auction body. --Mark "keller.schaefer" <[EMAIL PROTECTED]> wrote: >Does any body know of a Pentax 28-80/2,8 (!) sold only in the USA and >Switzerland - at least that is what the (Ebay) seller claims (and still >does, even after being specifically asked). bdimitrov.de doesn't have it, >but it would surely be an interesting lens... >Probably just another example of "Sorry, I don't know nothing about >photography - found these parts in a drawer..." - or maybe not? > >Sven
