I am selling my SIGMA LENS because I have arthritis and it is just to heavy for me. I am goin you go with a 100-400 instead. I paid 759.00 for this in December. I will sell it for 550.00 and I will pay shipping to lower 48 states by ups. It does have a filter on it and comes with a case. I do have the box as well. I am just past the 30 day return policy at Adorama, Sony procrastination is your lucky day. I take pay pal only and will ship immediately.
I sent you a PM.
