I've had this lens about four years. I sold my camera two years ago because someone was begging me for it, but I kept the lens thinking I would buy another camera, and just haven't done it. It's been in the bag and box in the closet.
It was used to take photos on the sidelines at college football, baseball, and basketball games. I was promoted at work, and became to busy to spend the extra time needed to continue the hobby.
If anyone is interested, I'm willing to ship to any of the lower 48 for $600.00.
The lens is in excellent condition and was taken very good care of since I had to buy my own equipment unlike some of the other people in the field. Very little wear near the base on the right side, where I use to prop it up while shooting. Other then that flawless.
