Olympus E 9-18mm f/4.0-5.6 Zuiko Lens for Olympus Digital SLR Cameras by Olympus

.Olympus ED 9-18mm 1:4.0-5.6 Lens: Highly Recommended by dpreview.com

The Zuiko Digital ED 9-18mm 1:4-5.6 is without doubt a very good lens indeed, especially for a relatively inexpensive ultra-wideangle zoom. It's sharp even wide open, has negligible distortion, and shows practically no vignetting. Indeed it's a delight for pixel-peepers looking for high levels of sharpness right across the frame; there's little of the drop in sharpness towards the corners that is often encountered with wideangle zooms. The only visible optical flaw is lateral chromatic aberration, but this is pretty well inevitable for this type of lens, and while red/cyan fringing is visible in many circumstances it's not really any worse in than we'd expect.
