Canon 55-200mm Lens
ANy one in the group using this lens? If so, I would like you views on how you like it and its optical and build quality. I realize this is an inexpensive zoon so I am not expecting 'L' quality here. Also I saw a review on another site where the person was complaining about viginetting with this lens. Since this is a regular EF lens, I don't see how you can have viginetting with a 1.6x crop factor but that was one of his complaints. Any one experice anything like this with this lens.
