I know I've been quiet on here for some time, but I really need some opinions on this matter. I've been looking for an affordable telephoto lens for my Pentax K1000 for a while, and today I stumbled upon a Phoenix 500mm f/8 telephoto lens for $99.95 on Amazon. I was wondering if it was even possible to get a good lens for that price. I just don't have a whole lot of money to spend on a Pentax telephoto lens and any out would help a lot. Thanks.
