random post in here, but it might generate more interest than a sale thread.
i have a spare 50mm f2-22 pentax k mount lense. really nice glass, nice smooth focus ring.
id let it go for pretty cheap, someone hit me up if they want it.
you can get an adapter for super cheap on ebay and use it with any 1.6 crop canon, you just cant use it with a full frame because the mirror hits it. (ive read that by modifying the lense you can do it, but thats at your own risk)
also would work with any pentax dslr.
dont think it works with nikon because the flange to sensor difference isnt right, so you cant focus to infinity
but anyway, drop me a pm if someone wants it, otherwise ill just hang onto it as a spare in case i god forbid destroy mine.
