Tokina 17mm 3.5 for nikon. The focus ring has a little bit of play in it, but it does not effect the performance. The glass is mark free and the lens is in good shape. Throw a nikon to eos adapter on and you have a nice wide angle for your t2i/7d/60d/5d
I have also "De-clicked" the lens, which means that the aperture ring turns freely without clicking into place. This is especially nice if you are using it on a DSLR for video. It allows you to split your f stop and really dial in exposure. If you want, I can put the spring back into the lens before shipping it.
$140 and I'll pay shipping
