Best lens I have ever owned. I bought used from a national geographic photographer a couple of years back for $700 best investment I ever made. It (hints why its so cheap) does come with a couple of flaws. The original glass was replaced when she owned it and sometimes it gets stuck when focusing at 200 mm you just have to twist the focus ring and it works again. besides that, I used this lens for weddings, portraits and so much more. its an amazing piece of glass and needs a home now that I switched brands. You are welcome to try it before you buy it. call text at {contact info removed}
