The Olympus M.Zuiko ED 100-400mm F5.0-6.3 IS ($1,499.99) is an appealing lens for Micro Four Thirds photographers interested in capturing photos of distant action. It's built to high standards, made for all-weather use, and offers teleconverter support. And despite an ultra-telephoto angle, it's quite useful for handheld photography. That said, its optics are a mixed bag—we enjoyed sharp results at the wide end, but quality drops off when zoomed in. For the price, we hoped for better.Ultra Telephoto for Micro Four Thirds Olympus has a few telephoto zoom options for the Micro Four Thirds mirrorless system. The M.Zuiko ED 100-400mm F5.0-6.3 IS qualifies as midrange in price and position. It's a step up from the $550 75-300mm F4.8-6.7 II, and well shy of premium options like the $2,900 M.Zuiko 300mm F4.0 and the $7,500 150-400mm F4.5 TC 1.25X IS Pro. From the outside it looks great.

While its two stops slower than the M.Zuiko Digital ED 300mm f/4.0 IS PRO lens at the 300mm focal length, the M.Zuiko Digital ED 100-400mm f/5.0-6.3 IS lens offers a more versatile alternative that is smaller, lighter and more affordable.

First off, there is no doubt that Olympus have produced a superb lens, both for ease of use and for features provided. Performance is also excellent, better than the bald figures suggest. The IS system works well, extending the usefulness of the lens as the light levels fall.

Variable aperture with a maximum of f/5.6-6.3, Stabilisation not compatible with Sync IS

The OM System/Olympus M.Zuiko Digital ED 100-400mm f/5-6.3 is a ultra-telephoto zoom that handles quite well although there are some niggling points. For example, the lens’ various switches are more awkward to get at when shooting in the portrait format.
