This is a review of the Olympus Zuiko Digital ED 50-200mm f/2.8-3.5 SWD camera released recently. The Olympus Zuiko Digital ED 50-200mm f/2.8-3.5 SWD is a fast and robust telephoto zoom lens for the Four Thirds system. Offering an angle-of-view range similar to that of a 100-400mm lens on a 35mm body, the Zuiko Digital ED 50-200mm f/2.8-3.5 SWD boasts a dust- and drip-proof construction, a Supersonic Wave Drive auto-focus motor and an iris diaphragm with 9 rounded blades. The optical formula comprises 16 lens elements arranged in 15 groups, including no less than 3 ED glass elements. Supplied with a tripod adapter, lens hood and case, the Olympus Zuiko Digital ED 50-200mm f/2.8-3.5 SWD is currently available for £979 / $1,199 in the UK and the US respectively.

Weighing in at nearly 1kg, the Olympus Zuiko Digital ED 50-200mm f/2.8-3.5 SWD is certainly not a lightweight lens, but for the focal range and fast maximum aperture on offer it is actually a pretty compact unit. Build quality is excellent, as you would expect from a lens in this price range.
