Ultra compact, light-weight

The lens size has been dramatically reduced thanks to the short flange back distance of the Micro Four-Thirds format (approx. 50% shorter than that of the Four-Thirds format) as well as the retractable lens mechanism design. When compared to the Zuiko Digital ED 9-18mm F4.0-5.6, its volume is 50% smaller, and mass is 60% smaller. Ultra-compact, this is a lightweight lens you have never seen before.

  • The flange focal distance is the distance from the lens mount (metal ring) on the body to the image sensor plane.

High image quality achieved by an optimal lens design incorporating advanced processing, manufacturing and measurement technologies.

Ultra-compact, lightweight lens deveoped based on many years of experience in lens design, processing, manufacturing, and measurement.

Lens design technology

Comes equipped with two DSA lenses, a world first. To provide high image quality while keeping the small size, this lens features an ideal, logical lens design in which 2 DSA (Dual Super Aspherical) lenses located in the front capture the 100° wide angle and a dual aspherical lens located on the back correct aberrations.

DSA (Dual Super Aspherical) lens

Olympus was the first company in the world to successfully mass-produce Dual Super Aspherical Lens. This lens features an extremely large thickness ratio between the centre and periphery.

HR (High Refractive index) lens

This lens features high refractivity and high spherical aberration correction capability. When combined with ED lenses, it can dramatically reduce chromatic/spherical aberrations.

Lens processing technology

Advanced lens design requirements demand highly-precise manufacturing technology. Olympus has developed an original manufacturing (thermoforming) technology for large aperture DSA lenses to create aspherical glass mould lenses.

Concave meniscus dual aspherical lens

Concave meniscus dual aspherical lens

This technology was also used for the Zuiko Digital ED 9-18mm F4.0-5.6. Olympus is the only company who has highly precise thermoforming technology for over 30mm large aperture lenses.

Dual concave aspherical lens

Dual concave aspherical lens

For the first time, Olympus has created a dual concave aspherical glass mould lens. With a significant aspherical shape, curves at the periphery are tough, making high-level forming technology necessary. Lens surface balancing is strictly controlled, maintaining balancing accuracy on micron-order scale.

Lens assembly/measurement technologies

High-precision lens fabrication requires high-precision measurement technology. In order to satisfy design requirements, we make use of our shape measurement technology for DSA lenses and surface eccentricity adjustment technology.

Surface accuracy of dual concave aspherical lenses

Actual measurement data for moulded surfaces

The vertical axis shows the manufacturing error from the aspherical shape design values. We have successfully controlled the shape of the part shaped like the bottom of a pan to ensure the required lens performance. We achieved the shape accuracy of 0.1μm (1/10000mm) or less.

Dual concave aspherical lens surface eccentricity

Lens surface eccentricity

The angle difference between the optical axis of the left side surface (red) and that of the right side surface (blue) is called surface eccentricity. We have developed a moulding system that can precisely control the positional relation of the moulds used to form both side of the lens at high temperatures. This guarantees the quality of the lens.


The newly-developed MSC (Movie and Still Compatible) mechanism provides fast, quiet AF for both movies and still images.

Olympus enhanced the inner-focusing system of interchangeable lenses adopted by conventional SLRs. A screw drive mechanism is used for the drive method for quick, smooth, quiet, high-precision AF (autofocusing). By using the latest optical designs to ensure a minimum number of lens elements for focusing, a lighter lens is achieved. A single lightweight lens is used for focusing in the ED 9-18mm F4.0-5.6.

Adopted a sub-micron precision metallic shaft and feed screw (screw drive) mechanism

The gears have been removed, eliminating operational noise. A sub-micron precision metal axis (shaft) and feed screw are used for efficient, direct driving of the lightweight focusing lens. Enabling faster and quieter autofocusing.
