Canon EF-S 10-22mm f/3.5-4.5 USM Lens, about 2years old. This has been used but is in good order but could do with a clean although there is absolutely no dust which affects photos - none on lens. The only thing which is a problem with the lens is that the viewing glass for the focal range is cracked. This in no way affects the usability of the lens but is just not quite as aesthetically pleasing as a new lens!! Please see picture.
