For sale is my barely 6 month old Sigma 17-50 f/2.8. I picked up this lens when I upgraded to the D7200. It's a great lens and in great shape. The reason I'm selling is because I found a fantastic deal on the Nikon 17-55 f/2.8 and I simply could not pass up on the price ($550 for near mint condition if you must know ).
Box and all accessories included, lens has had a filter on since day 1, but is not included.
