Rated 4.5 out of 5 stars by 10 users at B&H Photo Video

"Excellent - fast, perfect zoom range, and quality of image with this zoom lens speaks volumes. Reasonably priced. 18mm-50mm range is a perfect "Default" lens for quick shooting. A super alternative to more pricey Zuiko lenses."

"I just returned from a trip to San Francisco and was very satisfied with the performance of the lens. It worked well for street shots in Chinatown as well as wide angles at the Golden Gate bridge."

"the only one think I dont like so far is the front cap, hard to clip on when hood is attached."
