Quote: Ya, I've seen some decent 67 prices. But my PK and M42 midrange teles (180-300) didn't cost much either, the priciest being: Vivitar Series.1 200/3.5, $52; Super Takumar 200/4, $37; Jupiter-21M 200/4, $24 new - all including shipping. Maybe the next time that 1) LBA hits me and 2) I have disposable money and 3) I'm back at my permanent address, I'll revisit eBay for MFs. Or maybe I'll just wander into the right pawnshop and be swept away, eh?
Yes, you are right. Pentax, with this incredible thing called backwards compatibility, makes all kinds of options available to us. The Medium Format, though by no means an obvious lens choice for DSLR, is just another choice for the user. The level of autonomy which Pentax brings to its user is why I hold the brand in such high esteem--it separates them from the competition.
I picked up the 67 165mm f 2.8, in Mint condition, with mint case & original packaging for under $90--shipped. I also bought the highly-rated 67, later model 55mm f4 and later model 67 200 f4mm, close focus model. If I ever get serious about extra large enlargements, I would likely go to one with one of these lenses for the absolute uniformity in image quality they brings to the table. Surely a niche lens!
