Pentax USA only has 6x7 teleconverter, nothing else for 645 or 6X7
That FA 35mm f3.5 645 has been out of production for years.
Why not see what Pentax Canada can get for you from their historical 645, 6x7 listings.
I remember buying my first K-Mount dslr in 2006, &being excited about locating new Pentax made glass, &placing inquires with local shop and being told nothing was available after they called Pentax Colorado headquarters. Even though the lenses were in current Pentax catalogue.
Deja-Vu
Originally posted by smc Pentax Canada lists all of the 645 FA lenses....of course it doesn't help much as they don't have a web store. They can probably order it in though (they just brought in a new focus screen for my 67II without any problem)....
