I bought this lense a month or so ago. I find it great for portraits but I'm not adept to manual focusing on sports. As for weddings which is why I primarily bought it, I think it would slow me down because it needs to be mounted on a monopod. I already own the 135mm f/2 as well.
It has one minor scratch on front element that does not affect image, and a little brassing. I would rate the lense 8+.
Otherwise $1750is my asking price. Comes with a soft cover and HE4 lens hood and I'll cover S+H.
