I was at the camera store today and saw this lens. It is absolutely tiny given its focal length range. I'm not thrilled with the idea of a 5X zoom and its compactness and variable maximum aperture tell me a few things about its design that don't appeal to me. But it is incredibly small. I rarely carry my 80-200 f2.8 because it is so heavy and bulky. This might be an answer for me. Any reviews?
