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, this lens will make super-wide-angle photography friendlier and more affordable. It's all thanks to the DSA (Dual Super Aspherical) lens, available only with the Four Thirds System. 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.
