Olympus M Zuiko ED 9-18mm f/4.0-5.6 Lens

Until now, super-wide-angle lenses tended to be big, heavy, and expensive, making it difficult for most camera users to take advantage of them. The ZUIKO DIGITAL ED 9-18mm F4.0-5.6 promises to change all this. With its ultra compact and lightweight design and the outstanding portability, thanks to the DSA (Dual Super Aspherical) lens, available only with the Four Thirds System, this lens will make super-wide-angle photography friendlier and more affordable. Despite its compact size it's just 73 mm long and weighs a mere 280 grams this lens boasts a long focusing range equivalent to 18-36 mm on a 35-mm camera lens.
