"In summary, then, the M Zuiko Digital 9-18mm F4-5.6 is an impressive little lens that packs a lot of capability into a body that's sufficiently small you can carry it around with you all the time, and therefore actually use it. It's a great match for the rangefinder-style Micro Four Thirds bodies in particular, giving ultra-wide capability with unparalleled portability. It's a lens which, we suspect, will be especially attractive for landscape and travel work. Overall, it's a fine addition to the Micro Four Thirds system. "
