Reception

Reviewers have praised the lens for its 11.1x focal length range, effective vibration reduction, excellent autofocus motor and its versatility. However, the lens has been criticised for pronounced and complex distortion across the range, extreme softness at certain focal lengths and

. Overall, it has garnered generally positive reviews, citing the lens' flexibility and ability to "allow the photographer to travel light and never miss a shot while changing lenses".

Problems

The lens has problems with auto-focus of near subjects and in wide-angle position of infinity subjects on some older Nikon digital camera bodies. The problem occurs in Nikon D 300 S also. The slow auto-focus problem can be solved in new DSLR cameras disabling the light bulb guide that's built in the body camera. Enabling only one point of focus and enabling "continuous engine focus" or "automatic" instead of single servo, may speed up auto-focus greatly to normal again.
