With a zoom range covering the most in-demand wide-angle focal lengths, the first thing that will strike you when you pick up this remarkable lens is its amazingly small dimensions and light-weight. The M.Zuiko 9-18mm is the smallest ultrawide angle zoom lens in the industry today.
 

Whilst diminutive in size, it packs a formidable optical punch with outstanding sharpness and contrast from 18mm through 36mm (35mm film format equivalent) zoom range. Olympus has used some of the highest technology glass usually reserved for professional SLR lenses in this lens design, with twin DSA (Dual Super Aspherical), Aspherical, ED (Extra Low Dispersion), and HR (High Refractive) lens elements.
 

The MSC lens drive technology used for autofocus provides new levels of auto focusing performance, permitting fast autofocus speed and the smooth and silent operation desired for movie recording.
