The-Digital-Picture have reviewed the Sigma 18-125mm F3.8-5.6 DC OS HSM, a high ratio zoom lens designed exclusively for digital SLR cameras.

“My experience with this lens’ autofocus accuracy has not been the best. I am getting the best results from the widest angles with hit rates deteriorating as the focal length increases. Even the relatively wide DOF (Depth of Field) delivered at this lens’ max aperture are not enough to hide the inconsistencies. Shooting at f/8 or f/11 gives me better results - better hiding any AF errors with deeper DOF. “
