Olympus M.Zuiko digital ED 8-25mm 4.0 PRO

The Olympus 8-25mm f4 Pro is a fresh and very welcome addition to the Micro Four Thirds system. There’s lots of ultra-wide or standard zooms in the catalogue, but few that effectively cover both ranges. The earlier Leica DG 8-18mm started very wide but often left you wanting to zoom a little longer. Then the Leica 10-25 sacrificed a little at the wide end to extend further while delighting with its bright and constant f1.7 aperture, but this made it a heavy and expensive option for most of us. With the 8-25mm f4 Pro, Olympus has successfully filled the gap between the two Leicas, starting as wide as one and ending as long as the other, but opting for a more modest f4 aperture to keep the size, weight and cost down. The retracting mechanism also allows the lens to shrink to a compact size without getting in the way of operation. The result is a lens that delivers a very flexible range from ultra-wide to standard coverage with useful close-up focusing and a compact size. Sure the f4 focal ratio on Micro Four Thirds means you won’t be enjoying shallow depth-of-field effects unless your subject is very close, but that’s about the only sacrifice to achieve what’s arguably one of the most compelling walkaround lenses in the system. If I had to choose just one lens for general use on a Micro Four Thirds body, the Olympus 8-25mm would be it, and it comes highly recommended.

The Olympus M.Zuiko Digital ED 8-25mm F4 Pro is a versatile lens with no direct peer. It offers a wide-angle to normal field-of-view, and while not as bright as some of its similar competitors, the constant F4 aperture makes it useful for everything from landscape to street to travel photography. It's sharp wide open, and optical aberrations are kept to a minimum. Speedy and silent autofocus along with a lack of focus breathing make the lens a great option for videographers as well.
