Released in July 2011. *Micro Four Thirds lens. A wide-angle lens with a 24mm (35mm equivalent) aperture, offering excellent image quality with high contrast and sharpness across the entire frame, even at F2.0. Mount: Micro Four Thirds mount. Focal length: 12mm (35mm equivalent: 24mm). Maximum aperture: F2. Filter diameter: 46mm. [ED12MMF20] ED12MMF20. Released in July 2011. The M.ZUIKO DIGITAL ED 12mm delivers compact size, high performance, and superior image quality through the combined efforts of skilled artisans and cutting-edge technology. The F2.0 lens employs 11 elements in 8 groups, including two aspherical elements, including a DSA (Dual Super Aspherical) lens, which effectively corrects various aberrations and allows for compact lens size, but requires highly precise technology due to its extremely large central-to-peripheral thickness ratio; a Super HR (Super High Refractive Index) lens, which provides excellent spherical aberration correction; and an ED (Extra-Low Dispersion) lens, which effectively corrects chromatic aberration. The well-balanced arrangement of these elements achieves high contrast, sharpness, and exceptional image quality across the entire frame, even at the widest aperture of 12mm (24mm in 35mm format) and F2.0, all in a compact design with a maximum diameter of 56mm, total length of 43mm, and weight of 130g. Furthermore, the lens surface is newly coated with ZERO (Zuiko Extra-low Reflection Optical) coating, which offers high transmittance and thoroughly eliminates previously difficult-to-prevent ghosting and flare, ensuring clear imaging performance even in adverse conditions such as backlighting. ZERO Coating is a coating technology developed from thin-film control techniques accumulated through the development of multilayer film deposition techniques for microscopes. Development and manufacturing of this lens would not be possible without extensive design know-how, measurement techniques for accurately evaluating surface accuracy, advanced ultra-high-precision aspherical molding technology, expert polishing techniques, and ultra-precise assembly techniques. The high-quality texture of the metal exterior, a sophisticated form, and a design exuding a sense of compactness. The metal exterior's hard, pleasant feel and the sophisticated form exuding the sense of compactness unique to precision instruments were designed with the desire to create a product that will be cherished for generations to come. Its ambiance conveys a sense of high performance at a glance, and expresses the allure of the combination of light, technology, and minerals. Pairing it with the OLYMPUS PEN E-P3 creates a timeless look. Newly adopted "Snapshot Focus Mechanism" that shifts the focus to a specified distance by sliding the focus ring toward you The M.ZUIKO DIGITAL ED 12mm f2.0 is equipped with a new mechanism called the "Snapshot Focus Mechanism" that takes advantage of the wide-angle lens's unique characteristics for snapshot photography. This mechanism shifts the focus to a specified distance by sliding the focus ring toward you, and rotating the focus ring moves the focus position to the distance scale engraved on the lens barrel. By using this mechanism, for example, by setting the camera's mode dial to A or M mode, the aperture value to F8.0, and the focus position to 3m, you can achieve pan-focus photography with both the foreground and background in focus, making snapshot photography even easier and more enjoyable. ■ Specifications ■ Mount standard: Micro Four Thirds System standard Focal length: 12mm Lens construction: 11 elements in 8 groups (1 DSA lens, 1 aspherical lens, 1 Super HR lens, 1 ED lens, etc.) Angle of view: 84° AF method: High-speed imager AF (MSC) Minimum focusing distance: 0.2m Maximum magnification: 0.08x Closest focusing range: 162 x 216mm Number of aperture blades: 7 (circular aperture) Maximum aperture: F2.0 Minimum aperture: F22 Filter size: Φ46mm Size (maximum diameter x total length): Φ56 x 43mm Weight: 130g Accessories: Lens cap (LC-46), lens rear cap (LR-2), instruction manual, Olympus international warranty card □ * Lens for Micro Four Thirds
