For sale is a canon 28-135 lens F/3.5-5.6. It is the kit lens that comes with canon dslr's so i doubt there will be any interest for it. It has an EF mount so it will fit canon 5d, 7d, rebel series, t2i, etc.

I am selling this lenses because i upgraded from the one lens quiver. Very minimal use on it. 700 pictures and less than 20 minutes of video use.
I'm no camera aficionado but i can answer most questions if you have them.
