A new standard for high-quality standard zoom lenses, evolved with the latest technology. Mount: Micro Four Thirds mount. Focal length: 12-40mm. Maximum aperture: F2.8. Filter diameter: 62mm / [ED1240MMF28PROII] ED1240MMF28PROII Released in March 2022
High resolution and compact size. This large-aperture standard zoom lens covers the wide-angle to medium telephoto range, achieving both high resolution and compact size.
High resolution. The excellent lens design delivers outstanding imaging performance. This high-performance lens fully utilizes the camera's high-resolution shot function. The lens design, with 14 elements in 9 groups (including two ED lenses, one EDA lens, and two HR lenses), delivers outstanding imaging performance despite its compact size. The strategic placement of four aspherical lenses, including a DSA lens, effectively corrects aberrations caused by zoom fluctuations, achieving high resolution from the center to the edges of the image throughout the entire zoom range.
ZERO Coating The lens surfaces are treated with ZERO (Zuiko Extra-low Reflection Optical) Coating, which provides high transmittance and thoroughly eliminates previously difficult-to-prevent ghosting and flare. The coating placement has been optimized to deliver clear images even in backlit situations.
Reliable Environmental Resistance The lens boasts dust and water resistance (IP53) and freezeproof performance down to -10°C, ensuring worry-free use in harsh environments.
Dust, Water, and Freezeproof Performance The lens boasts excellent dust and water resistance (IP53) and freezeproof performance down to -10°C. When paired with a camera body that is dust, water, and freezeproof, you can continue shooting with confidence even in harsh environments such as rain, snow, and dusty conditions. Fluorine Coating: The front lens element is coated with a smooth, scratch- and smudge-resistant fluorine coating. Even when shooting in rainy, snowy, or dusty environments, smudges can be easily removed with a blower or lens cloth, allowing you to continue shooting immediately. This standard zoom lens offers excellent macro performance with a maximum magnification of 0.6x (35mm equivalent), high-speed, high-precision AF (capable of 50 fps continuous shooting), and excellent operability. Macro Performance: A minimum focusing distance of 20cm from the image plane is maintained throughout the entire zoom range. At the telephoto end, close-up photography with a maximum magnification of 0.6x (35mm equivalent), exceeding half macro, is possible. Working distance: Approximately 9.4cm (Wide end) and approximately 6.6cm (Telephoto end). Even at the wide-angle end, you can get close to the main subject, enabling a wide range of applications, including wide-angle macro photography with exaggerated perspective. Depth Stacking: The focus stacking function automatically combines multiple images with different focal lengths. The high-speed, high-precision AF MSC (Movie and Still Compatible) mechanism is an advanced optical design technology developed to achieve fast, quiet focusing with a lightweight lens element count. By eliminating gears that cause operating noise and adopting a metal shaft finished to submicron precision and a linear motor drive system capable of accommodating quick movements, the focusing lens element is directly driven. The compact, lightweight focus unit, consisting of two cemented lenses, is driven by the MSC mechanism, resulting in agile and quiet AF operation. Enjoy stress-free, comfortable shooting with both still images and videos. The camera's advanced control technology also supports continuous shooting at 50 frames per second. Manual Focus Clutch Mechanism: The Manual Focus Clutch Mechanism instantly switches to manual focus by pulling the focus ring toward you. This is a convenient feature for quick shutter releases, such as when taking snapshots. L-Fn (Lens Function) Button: A button to which various functions can be assigned is located on the side of the lens barrel. Functions can be assigned according to the camera body's custom settings, including autofocus stop. Enjoy functions that suit your shooting style.
