I have a Tamron 17-50 F/2.8 that I need to get rid of cause I got some other equipment making this useless to keep around. I have probably used it about 10 times total and has been babied since day one. It comes with all of the paper work and original box if you were to order your own from B&H. I am looking for $350 obo. I will look at any trades for other photo equipment such as flashes, 85 f/1.8, 50 f/1.4, or something else of interest. Non-photo trades would be a 3rd generation iPod Touch.
