When you need wide angle lenses with great performance and fast apertures, Zuiko Digital Wide Zoom lenses can deliver. The superb optics are designed specifically for digital photography - delivering the highest image quality - with their design highlighted by two aspherical glass lens elements that help prevent aberrations and distortions. These elements combine with new multi-coating on the first two lenses, which contributes to the removal of ghost or glare that can occur with a wide-angle lens, so clarity of images is obtained at all distances. Floating focusing system results in close focusing distance of 0.28m (11.02 inches) for close-up macro shots. Ideal for professional use.
