Summary: An amazing lens, this packs every focal length you could need into one solid lens. I've used it for photojournalism and have produced some outstanding images. Sharpness is really good, AF speed is solid, and the lens is very compact when walking around. Having 450mm equivalent focal length is great for sports and wildlife. I highly recommend yo try this lens.
Excerpt: I use this product to film weddings but only when I'm in a pinch. It's slow and not very good for low light situations. It is useful when you can't get close enough to the subject (large Catholic Church etc.
Excerpt: Good, all purpose walk around lens - can be used in almost any circumstance. Good sharpness through range. Just a bit "clunky" in autofocus at times, but nothing major. Still getting used to variations in depth of field through range but that is probably more a matter of practice than a problem with the lens - it has a very extended zoom range.
Pros: Easily Interchangeable, Lightweight, Strong Construction
