Olympus M.Zuiko 17mm/1.8

Achieving high-image quality/high-performance and compact size

9 elements in 6 groups, including a DSA lens that incorporates highly-accurate production technology; and an HR (High Refractive index) lens, that features high spherical aberration correction capability, are packed into a 35.5mm, 120g compact body. Boasts sharp, high-contrast image throughout the image area even at F1.8 aperture. State-of-the-art technology and know-how acquired through years of experience made it possible to achieve this level of image quality and high performance whilst ensuring a small size.

ZERO Coating eliminates ghosts and flares

ZERO (Zuiko Extra-low Reflection Optical) Coating is applied to the lens surface to eliminate ghosts and flares that used to be difficult to reduce because of their high transparency. ZERO Coating boasts clear image quality even under challenging conditions such as backlit conditions.

The MSC (Movie and Still Compatible) mechanism enables fast, quiet autofocusing

The high-precision axis hanging method supports the MSC mechanism
The MSC (Movie and Still Compatible) mechanism is the latest in optical design technology for achieving fast and silent focusing with a lightweight form and minimum number of lenses. The gears have been removed, eliminating operational noise. A sub-micron precision metal axis (shaft) and feed screw (screw drive) are used for efficient, direct driving of the lightweight focusing lens. Enabling faster and quieter autofocusing.. This lens employs an inner focusing system that uses the MSC mechanism. It performs autofocusing by optimally controlling the three small, lightweight lenses. Thanks to this smooth AF system, users can comfortably shoot both still images and movies.
