Hermetically sealed with materials that are breathable yet protect against the ingress of dust and splashes, this lens has a construction that allow use in harsh environments. A mere 285 g weight is achieved for excellent portability while maintaining the high-powered zoom.
35mm equivalent: 28mm (x1)
35mm equivalent: 84mm (x3)
35mm equivalent: 140mm (x5)
35mm equivalent: 300mm (x10.7)
0.44x magnification (35mm equivalent) tele-macro photography is achieved. This feature is useful for background defocusing effects.
A lens design of 15 elements in 11 groups (DSA lens, EDA lens, ED lens, HR lens, E-HR lens, etc.) enables a compact form with an excellent depictive performance at all zoom ranges.

Olympus' highly-transmittable ZERO (Zuiko Extra-low Reflection Optical) Coating is applied to the lens surface to eliminate previously hard-to-prevent occurrences such as ghosts and flares. ZERO Coating boasts clear image quality even under challenging conditions such as a backlit condition.
A screw drive mechanism is used for quick, smooth, quiet, and high-precision autofocusing. The MSC mechanism incorporated in this lens is the fruit of advanced optical design technology developed to enable autofocusing with a lightweight lens element.
The gears, which are the cause of operational noises, have been removed. A sub-micron precision metal axis (shaft) and feed screw are used for efficient, direct driving of the lightweight focusing lens. This enables faster and quieter autofocusing.
