I have had this lens since April and feel that it does not get enough use. It is in perfetc condition as it has literally been on my Nikon body 4 times. about 200 pictures taken and it is sharp. I am selling this or will consider trades for any similar quality AF-S lenses or sigma EX HSM lenses. I am looking to get 550 shipped. You can look at my ebay feedback under teh same username. If you are local to me in NJ 07065 you are more then welcome to come and check it out. I do not have a paypal account. I will agree to what ever method you would like. just drop me a note if you have any questions.
