Compact, Lightweight, and High Magnification: This single lens is perfect for everyday landscapes and snapshots, as well as travel and mountain climbing. It combines high magnification with a compact, lightweight design for easy portability, weighing just 411g. This wide-angle, high-magnification zoom lens boasts a compact, lightweight design weighing just 411g. Its high portability supports effortless photography.
Retractable Mechanism: This is the first M.ZUIKO PRO series lens to feature a retractable mechanism. This new mechanism allows the lens to be retracted simply by rotating the zoom ring, allowing for smooth shooting. The lens barrel has been retracted, eliminating the water-repellent lever, achieving IPX1-equivalent weather resistance. High Resolution Across the Entire Zoom Range: The lens construction, consisting of 16 elements in 10 groups, including special lenses such as Super ED, ED, and EDA lenses, thoroughly eliminates chromatic aberration and other aberrations. Despite its high 3.1x magnification, it delivers high resolution across the entire zoom range. Furthermore, the large DSA lens significantly reduces sagittal coma aberration, achieving excellent point image reproduction from the center to the periphery, even at maximum aperture. Complete Ghost and Flare Prevention: While this is an ultra-wide-angle lens with an equivalent focal length of 16, optimized optical design and coatings significantly reduce ghost and flare in backlit situations. Excellent Close-Up Shooting Performance: With a maximum magnification of 0.42x, approaching half-macro, you can get close to your subject and capture powerful photos. The minimum focusing distance remains constant at 0.23m throughout the entire zoom range, allowing you to freely adjust the size and perspective of your subject when shooting close-up. This lens boasts IPX1 equivalent weatherproofing, excellent dustproofness, and freezeproofing down to -10°C. When paired with a dustproof, weatherproof, and freezeproof camera body, you can continue shooting with confidence in harsh environments like rain and snow. Filter compatibility: A 72mm diameter filter can be attached to the lens tip. Enjoy a variety of creative possibilities with PL and ND filters. You can also protect the lens with a protective filter. Easy-to-hold design: The zoom ring is positioned forward, ensuring ample space between the lens and the grip. This ensures comfortable holding and comfortable zoom operation, even when paired with a camera body with a large grip, such as the OM-D E-M1 Mark III. L-Fn (Lens Function) Button: Press and hold to pause autofocus. Depending on the camera, you can assign other functions to this button. The L-Fn (Lens Function) button is located in a position that is easy to press with the left thumb, making it easy to operate while holding the lens.
