I recently found a Soligor 85-205 f/3.8 Macro lens for very cheap. I'm wondering if anyone has any experience with this lens or brand by chance. I have a D300s, so I think my camera will still auto-focus with it (not sure?). I've been looking for a macro lens and I just found this. Even though its really cheap, I don't want to buy it if it isn't worth it. Thanks!
