Verdict

The Olympus M.ZUIKO DIGITAL ED 40-150mm 1:4-5.6 R is a quite good entry-level telephoto zoom lens. It may not be a cracker in terms of delivered resolution but it is no show-stopper either. The image quality is quite impressive in the low to mid portion of the zoom range. At 150mm it is somewhat weaker but not terribly so. Image distortions are usually taken care of by the camera's auto-correction mechanism but technically they are only very obvious at 40mm anyway (in RAW data only). Vignetting is usually nothing to worry about either. Lateral CAs can get obvious at 40mm but they're not really an issue at other settings.

In terms of build quality you shouldn't expect wonders - the lens has been optimized for size and weight and as such it is a member of the all-plastics league. That said the manufacturing quality is actually decent. Thanks to Olympus' new MSC drive, AF operations are surprisingly fast and near silent making it also an obvious candidate for taking movies.

From a price/performance perspective, the Olympus is a viable choice but it stays short of the higher expectations from more ambitious users - also due to the small max. aperture which limits its creative potential.
