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.
Optical performance equals to the High Grade Lens ED 12mm F2.0

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.
Bright F1.8 aperture and in-body image stabilisation are effective under low light conditions
All Olympus OM-D and PEN cameras feature an in-body image stabilisation system. When combined with the fast F1.8 lens, blur-free images are easy even when shooting sunsets, low-light indoor scenes, and other locations where flash photography is not permitted (such as zoos and aquariums).
The MSC (Movie and Still Compatible) mechanism enables fast, quiet autofocusing
The high-precision axis hanging method supports the MSC mechanismThe 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.
The advanced snapshot focus mechanism lets you shift the focusing point to a specific distance.
The snapshot focus mechanism enables you to take snapshots easily. Sliding the focus ring towards you to a specific distance reveals the distance markers engraved on the lens barrel as the focus point moves to a point on the distance marker. This mechanism allows quick deep-focus shooting, in which both subject and background are in focus, and quick no-finder shooting.
