Originally posted by PPPPPP42 You should talk to a few of the more serious addicts on this board. I know there are a few that have collections that read like indexes of all Pentax compatible lenses. I'm talking three digit numbers for lens count where the first digit isn't always a one.
I have 30 Asahi-Pentax-made lenses. I have twice that many (each) of PK-mount and M42 lenses, and those make up about 1/2 my accumulation. I have 50 Fifties. And I'm a piker compared to some here. At least one, maybe two members, own more Fifties than I have lenses. And I've only been accumulating glass for under 4 years.
One might ask, "If only half the lenses are PK or M42, what are the others?" Well, they're stuff I've adapted or modded for PK or M42, or that I mount in bellows or tubes, or that are auxiliaries like the Raynox. I have very few lenses left that I can't mount on my K20D. Most such unusable glass gets sold off -- that's another 120-odd lenses. They help pay for the keepers, eh?
[ ObTopic: And of what I have left, about 95% will project a FF image. ]
I suspect that others here have also had hundreds of lenses pass through their hands. Keep some, sell some, buy some more, see what works and what sings and what sucks. Keep some luzers until maybe they're worth selling in a year or three.
Lenses are not magic. They're tools. Some are works of high craft. I must keep those!
