from CAMETA Summary: This was part of the two lens kit that Sigma offered that combined the 18-50mm 3.5-5.6DC and 55-200mm 4-5.6DC lenses.
Perhaps expectations were unrealistic with this lens, after using the companion from the kit, the 18-50mm. The lens feels cheap, is not smooth and in fact, it binds at places in the zoom. This might be a convenient length, for the cost if nothing more, but recent experience with wide to telephoto zoom combos leave this lens as an odd man out.
The copy I received displays significant Chromatic Aberration under a variety, but not all, lighting conditions and for significant aperture ranges. It is prominent enough to eliminate this lens from most any use other than casual snapshots.
It has adequate AF performance. Outdoors under bright light with good contrasted subject, it still is not 'speedy'.
The lens produce reasonably sharp images with little corner fall off at the short end but more so towards the long end of the tele/zoom.
As part of a kit to get a longer lens for a Digital camera, it is only O.K. You might get a better copy than I did.
The hood is cheap plastic and started to warp a bit in sunlight after just a few minutes.
I can't really recommend this lens other than as starter for a short time. It will produce probably an equal photo to most point and shoot lens that are in the same zoom range. There is too great a possibility for disappointment in the resulting photographs produced with this lens. Save your money or purchase the 18-200DC lens that Sigma is producing. Strengths: Good color rendition except as noted.
Metal mount. Weaknesses: Chromatic aberration! (purple/colored fringing).
Zoom binds.
Plastic lens hood and awkward in design.
Corner Falloff that is erratic in intensity across the zoom range. Similar Products Used: Recently used extensively Sigma's wide to telephoto zooms in these lengths

Customer Service: Not needed for this product, but past experiences with SIGMA have been very positive and they respond well via email.
