I am selling a barely used (100 shots tops) Sigma 17-35mm 1:2.8-4 Canon mount lens. The story behind the lens is quite simple...I received it as a gift, used it a few times but ended up finding a great deal on another lens, hence me selling this one. This is a great lens, especially those who are trying to get into a wider variety of lenses w/o spending the big bucks for a Canon wide angles. The price is set at $350+shipping. If you have any questions ask away. I will post up pics very soon.
