Product description
The Zuiko Digital 11-22 millimeter f2.8-3.5 features two aspherical glass lenses that minimize distortion, spherical aberration and "Koma" aberration. A new multi-coating process applied to the first two lenses helps remove ghosting and glare, problems often associated with wide-angle lenses. The 11-22 millimeter focusing system also utilizes a floating mechanism to deliver sharp, high contrast images up to the lens' closest focusing distance, 0.28 millimeter (11.02 inches) at any zoom setting.
