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, this lens will make super-wide-angle photography friendlier and more affordable.
