A short while back I found this Rokinon 80 - 200mm Zoom Macro lens in our thrift store. My first clue that something was wrong was that it was packed in the box for an old point and shoot pentax camera.... The Rokinon lens was broken but I paid the 3 dollars for it anyway, figuring that I could play around with it; take it apart and use it for something.
And something I have. Today I disassembled the lens, and discovered that without the zoomy bit - the lens itself fits snugly over one of my other lenses. And makes a decent little macro lens for extreme close up photography.
