Negative Positive
Title: slightly dis appointed
Review: After reading some very good reviews of this lens, I was very diaappointed to see dust inside the lens, including a fairly large spot, within days after getting it. The distortion around the edge was quite noticeable. With a lens costing this much and comparison to "L" lens, I never expected this. Canon needs to improve its quality control. I, too, believe that a lens hood should have been included at this price.
Is the review positive or negative?
