A versatile lens with excellent imaging performance. Unlike zoom lenses, prime lenses are optimized for a single focal length, achieving both high imaging performance and compact size. The 34mm equivalent focal length provides a comfortable angle of view for smartphone photographers. The M.ZUIKO DIGITAL 17mm f/1.8 II minimizes the peripheral distortion often associated with wide-angle lenses, enabling natural-looking images from distant landscapes to close-ups. Weighing just 112g, it's incredibly light and portable, making it ideal for capturing street-level snapshots, or taking it on hikes and other outdoor adventures to capture the beauty of nature.
Leveraging the large F1.8 aperture to create bokeh: Using bokeh is an essential element of photographic expression, highlighting the subject or softening the overall atmosphere of the photo. By taking advantage of the large F1.8 aperture to blur the foreground and background, you can make your intended subject stand out. At the same time, by taking advantage of the wide depth of field characteristic of wide-angle lenses, you can enjoy pan-focus shots where everything from the foreground to the background is in focus. This lens is ideal for snapshots and landscape photography where you want to capture clear backgrounds and foregrounds. Lens design for clear, sharp image quality. To minimize aberrations, the 9-element, 6-group lens construction utilizes DSA (Dual Super Aspheric) lenses, HR (High Refractive index) lenses, and aspherical lenses, all of which require advanced manufacturing techniques. This allows for superior image quality while maintaining a compact, lightweight design with a total length of just 37.6mm and a weight of just 112g. Furthermore, the highly transmittant ZERO (Zuiko Extra-low Reflection Optical) coating thoroughly eliminates ghosting and flare, delivering crisp, clear images. Fast, quiet autofocus for both video and still photography. The focus group employs an MSC (Movie and Still Compatible) mechanism. Gears that cause noise are eliminated, and instead, a metal shaft and lead screw (screw drive) are machined to submicron precision. This optimally controls the movement of the three compact, lightweight focus lenses, resulting in fast, quiet autofocus.
Dust- and Splash-Resistant Design for Peace of Mind The M.ZUIKO DIGITAL 17mm f1.8 II is designed with IPX1 equivalent splash-proof performance and dustproof protection in mind. Because it's a compact, lightweight lens designed for easy portability, it's designed so you don't have to worry about your equipment getting wet. Not only is it ideal for landscape photography in natural settings, but you can also continue shooting snapshots if the weather suddenly changes, without worrying about it getting wet. In addition to its dust- and splash-proof performance, this compact, lightweight lens with a user-friendly angle of view makes it ideal for activities like mountain climbing where you want to keep your luggage light.
Lightweight and Portable Lens Its excellent portability means it can be carried around every day, allowing you to quickly capture unexpected photo opportunities. It can be easily stored and removed from a bag, even with the lens attached to a camera body like the OM-3, OM-5, or E-P7. This compactness and light weight are only possible with the Micro Four Thirds system.
