A typical ultra-wide-angle lens is usually large, heavy, and expensive, making it difficult for most camera users to get the best out of them. The
M.Zuiko Digital ED 9-18mm F4.0-5.6 II promises to change all that. With its ultra-compact
and lightweight design and excellent portability thanks to the DSA-
lens (Dual Super Aspherical), which is only available in the Four Thirds system, this lens
will make ultra-wide-angle photography more exciting and affordable. Despite
its compact size - it is only 49.5 mm long and weighs just 155 grams - this lens
offers a wide focusing range equivalent to that of a 35mm
camera lens with 18-36 mm.
