Canon EF-S 17-55 f2.8 IS USM in excellent condition with box. There is a very tiny bug (see pics) inside the lens and some dust marks.  Absolutely no effect on performance and neither are viewable on any pictures or on screen at any focal length.

Fully working with instant focus and excellent image stabilisation.

Canon front and rear caps 

Box is mint with inserts.

Superb lens with 'L' lens performance for APS-C and constant f2.8 aperture.
