The Olympus M.Zuiko Digital ED 9-18mm f/4.0-5.6 Lens is a super-wide-angle lens compatible with Micro Four Thirds System cameras. It offers a 100° angle of view, and overturns the rule that super wide-angle zooms have to be big and heavy. With a length of just 1.9" (49.5mm) and a weight of just 5.5 oz (155 g), it is less than half the size and 60% of the weight of the Zuiko Digital ED 9-18mm f/4.0-5.6. With its wide angle of view, it makes it easy to include background scenery in group photos, and can be used to create unique images with a sense of dynamically exaggerated perspective.
A Dual Super Aspherical objective element, used at the front of the lens, makes it possible for the lens to offer a 100° angle of view, and dual aspherical elements are used at the back, to correct aberration and ensure superior image quality. Thanks to efficient optical design, the lens delivers an uncompromising combination of compact size and high quality, with clear imaging all the way to the periphery.
