HANDS ON: At more than 3 inches in diameter, the lens is slightly wider than most f/3.5-6.3 digital-only superzooms (Sigma's measures 2.75 inches across). This portly girth is a little surprising when you consider that Sigma, Tamron, and Tokina boast longer zoom ranges (closer to 11X), and that they cover larger sensors. Otherwise, the Olympus is average for the class in size and weight. Like virtually all Zuikos, it appears to be very well-constructed, though it lacks focusing scales. The zoom and manual-focusing actions are extremely well-damped. AF action is fast and quiet, if slightly whiny.
