This lens is a great idea but poorly made. Does not produce quality images.

Summary: I have all Canon 'L' top of the line lenses which do a great job for me. But they are large - thought it would be nice to have a 'handy walk-about lens'. I used to have this lens in the non-VR days. I thought VR was going to make it a useful lens for walks & travel. But when it arrived it would not zoom past 125. (It was supposed to be 'refurbished'.) In spite of the zooming problem it should have produced sharper images in the non-affected range.
Summary: Bought this lens because reviews were great--it was stiff----and eventually failed-by literally falling apart---with a 1/4 size piece of metal falling into the actual camera body-nearly ruining my sensor-----This product is NOT durable--and despite being treated with extreme care-failed during its' inaugural shoot.--Not worthy of repair and a waste of money.
