Average Reviews:
(More customer reviews)I bought this lens so that when I travel using my Nikon D100 I could have an all-in-one zoom that would spare me the inconvenience of constantly changing lenses. I have not regretted this purchase, as for most situations the resulting photos are quite satisfactory. However, potential buyers should be aware that any lens that is designed to "do it all" involves compromises.
The lens balances well on an SLR body, is remarkably compact, and is well-made. It's not as solid, however, as an expensive professional-level zoom, so don't drop it! The petal-type lens hood works well to prevent routine flare.
Photos I have taken have been sharp and clear, with only a bit of softness at maximum aperture and at the longest focal lengths. The lens has a few shortcomings, however. In some lighting situations the color cast of digital images seems to be a bit "tan," tending almost toward sepia tones. This can be corrected easily enough in Photoshop (or whatever post-exposure program one uses). Perhaps a bit more annoying is that there is noticeable light falloff in the corners, a phenomenon that is most prominent in photos that include large areas of sky. Again, this can be dealt with in post-processing (mainly through slight cropping), but potential buyers should be aware of this issue.
The best thing about the lens is that it provides adequate performance at focal lengths ranging from standard wide-angle (what would be the equivalent of around 27mm. in a 35mm. camera) to basic telephoto (187 mm. at 35mm.) This makes it quite useful for general, "walkaround" photography, especially when one is traveling. If you want the absolute best in optical performance, however, you might find the lens wanting in some situations.
