I just purchased a Sigma 55-200mm f4-5.6 DC from ebay. Does anyone here already has this lens? I wanna know if any of you can post your picture(s) taken with this lens or any pros and cons. I've read some reviews and most of them had good things to say but still would like your opinion. One of the big reason I got lens is because I didn't have a "telephoto" lens before and the price was pretty decent.
