Originally posted by antipattern Is there any information on whether it's a new design or based on the Tokina 70-200? I wouldn't mind either, I'm just curious. The sudden appearance and a soonish release date (by Pentax standards) might be an indication of something - or not.
I don't think it would be based on the new Tamron 70-210mm f/4 Di VC USD, since that would imply it's more of a rebadge and they probably wouldn't drop those 10m at the long end...
Of course there is no official info for us. It would seem logical that it is Tokina, given that Tokina got licence for 50 mm and perhaps will be having 85&35 too(their new opera-line). So that Pentax could get some of these lenses for them. Lot of people says ’it is Tamron rebadge..’...for almost everything.
