The standard catadioptric Matsutov lens has been around for 60+ years. The design is so simple that just about anyone could make one, and they were popular until the 1980s. As I understand it, only Sony, Samyang, and Opteka make these mirror lenses for cameras these days. Samyang includes the brands Vivitar, Bower, Rokinon, and Pro-Optic.
I have recently bought items from deal extreme. they did arrive from quandong china after over 1 month even though I paid extra fast shipping! additionally there were of course customs and tax charges PLUS an intermediate company here in germany that charged an extra 25€ for their "services". So the deals are not that extreme anymore once the product actually arrives. Thanks for the good article MrAnthony! I also would advise to try b4 buy.
Tamron made a good one as well; the Minolta was designed to autofocus on a Minolta camera, so with an adapter, you'd lose AF and it'll be more expensive because it was designed to autofocus. There are some good mirror lenses, but by and large, they aren't as good as well-designed refractive lenses, which is why they fell out of vogue. Depending upon the individual lens, it is possible to find some off-brand mirror lenses which have good center sharpness and acceptable edge/corner sharpness.
