Sony CZ 24-70
I dropped a couple of lenses last year and they still work very well except the distorted physical shape.
Feel your Pain. I dropped mine about a year ago. It messed the zoom mechanism up. I sent it off to Sony repair in Texas. They charged a $ 400 flat fee which was worth it to me considering the price of a new one.
The lens was turned around in about 2 weeks and worked like new. I was very impressed with the service.
I would recommend letting a shop do the repair.
