For sale or trade is my Sigma 18-200mm f/3.5-6.3 DC OS lens for Nikon bodies. I am looking to pass on to someone who will actually use it as it has sat on my shelf pretty much since the day I bought it. I purchased it from a friend of mine a year ago with the autofocus NOT working and since I generally only use MF I never bothered to get it fixed. Again, the autofocus does not work. Other than that it is in impeccable shape and can take fantastic photos. I am looking to get around $230 but price is negotiable. Trade interests include SB series flashes, teleconverters, certain filters (77mm ND, polarizers, etc.). Paypal is accepted.
