Zuiko Digital 40-150mm F4–5.6 zoomlens for use with E-serie.

The Olympus Digital Zuiko 40-150mm f/4-5.6 ED is a budget class tele zoom lens in the Olympus lens lineup. It is usually sold as part of camera “kits” but it’s also available separately. Its focal length range is equivalent to about 80-300mm in full format (35mm) terms which should be sufficient for most amateur tele needs. A major feature is its amazingly small size and weight. It’s barely bigger than the dwarfish Olympus 14-42mm f/3.5-5.6 ED so it’s sometimes hard to distinguish between the two in your lens bag. It’s also substantially smaller and lighter than e.g. the comparable Nikkor AF-S 55-200mm f/4.5-5.6 VR (which isn’t big either).
