Nikon 10.5mm Fisheye f/2.8 - Used Twice, One Week Old ?

For sale is my Nikon 10.5mm f/2.8 Fisheye Lens. I had to buy this lens to shoot a concert after a hire company let me down at the last minute. As a result, I no longer need the lens and am selling it to buy a video camera. It comes boxed, with the receipt which can prove its purchase date (14th June 2012). Cash on collection only. Might also consider swapping with video camera equipment, however it would need to be good quality equipment for me to even consider it.
