On eBay. These weren't buried in wholesale lots -- these were straight-up auctions of the named lenses. Whenever I see a prospective lens come up with a low low low starting price, I make a low low low opening bid. Sometimes it's ludicrous. But sometimes I win. With the lenses I mentioned above, nobody else even made a bid.
HINT: Many want FAST FIFTY's. And few want SLOW FIFTY's. Absolutely superb lenses marked f/1.9 or slower may have very little demand, if any. Consider Super Takumars -- the 55/1.8 and 55/2 have exactly the same extraordinary optics, just a different maximum aperture stop. But I've seen f/1.8's sell for US$50 and f/2's NOT sell for US$10.
And consider the names. Folks are starting to catch on that lenses marked SEARS, FOCAL, VIVITAR, can be pretty damn good. But other generic 3rd-party brands are still sleepers. That Kalimar may indeed be a decent or at least interesting lens. Or it may be a total dog. For lens junkies like me, HEAVEN is getting a batch-lot of four no-name lenses for ten bucks.
