Originally posted by slackercruster I would love to use more extinct glass. But some of it is sooo hard to come by. That makes one careful sometimes and less prone to use rare lenses.
Hard to come by?!?!? It's literally DRIPPING off the vines at eBay! Much is overpriced. But much great stuff can still be had for a pittance. And much crud too, but here's a secret: Even crud doesn't lose value. If you get a cruddy lens, hang onto it for a month or ten and sell it for a profit. That works for me! Exception: the M50/2 never gains value.
Anyway, where to start? Look for the brands Focal (K-mart) and Sears. I've never had a bad prime with either label. Look for Vivitar (but check user reviews -- Vivs are variable). Look for Meyer, Lentar, Toyo|TOU, Enna, Rikenon, and Takumar of course. And look for cheap off-brands. Sometimes we get REAL lucky. And follow my bidding/purchase rules:
* If it costs less than a burger|sandwich, buy it. If it costs more than a supreme pizza, think hard about it.
* Bid low. Bid often. Lose 99% of auctions. Don't worry, another will come right along. They aren't rare.
