I have been using the 150 a lot and it is time to let go a lens that I don't use often enough to keep it around. I am the original owner and was purchased from Kurtland Photo a year back. 37 actuation only. Lens comes with front & rear cap, hood, box and paperwork. And it is in absolute mint condition. Asking for $2100. Please add 2.9% if using Paypal. Buyer will pay for shipping.
