A compact, lightweight S PRO series ultra-wide-angle zoom lens that delivers outstanding imaging performance. Mount: Leica Camera L-Mount standard. Focal length: 16-35mm. Max aperture: f/4. Filter diameter: 77mm. Dustproof and weatherproof. / [SR1635] SR1635 Released December 2019
Despite its large aperture, it delivers outstanding imaging power and beautiful bokeh throughout the zoom range. This ultra-wide-angle zoom lens in the LUMIX S series meets Leica's strict optical standards and delivers outstanding imaging performance with high resolution and three-dimensionality from center to periphery throughout the zoom range, despite its compact and lightweight lens design. This lens meets LUMIX's strict new standards, pursuing everything from soft bokeh and landscape photography, two of the joys of photography, without any compromise. The high-performance lens design, comprised of three aspherical lenses for suppressing spherical aberration, one ED lens for excellent correction of chromatic aberration, and one UHR lens, is comprised of 12 elements in 9 groups. Three aspherical lenses suppress spherical aberration, while one optimally positioned ED lens corrects chromatic aberration. The high-refractive index UHR lens delivers excellent imaging performance right to the edges of the image. Smooth bokeh with reduced vignetting and double-line bokeh, resulting in a natural, striking three-dimensional effect. This lens delivers smooth, beautiful bokeh with reduced ring lines, vignetting, and double-line bokeh. From dynamic landscapes with high resolution, to striking portraits with bokeh, and snapshots, this ultra-wide-angle lens delivers impressive, moving subject images in a wide range of scenes. Fast, precise focusing: The AF system achieves 480 times per second and contrast detection for high-precision focusing, while also achieving high speeds. It instantly detects contrast peaks and calculates the direction of movement and the focus position. Furthermore, by speeding up communication control between the body and lens, we've achieved both precision and speed.
Quick AF/MF Switching and Precise Focusing: The focus clutch mechanism allows for quick AF/MF switching by simply sliding the focus ring. A distance indicator appears on the lens barrel, enabling precise focusing.
S Series Lenses for High-Resolution 4K Video Production: The optical design for high-resolution video recording and an optimized internal lens barrel structure suppress breathing, which changes the angle of view as the focus position shifts during focusing during video recording. Furthermore, aperture micro-step control smoothly controls F-stop changes, reducing exposure changes even in scenes with large changes in brightness. It also supports stable exposure change control when panning during video recording.
Excellent AF Tracking Performance When Zooming: Autofocus performance is even faster when zooming, allowing for continuous focus. This is effective when shooting fast-moving subjects, ensuring you never miss a shot. Protect your lens even in harsh shooting environments with the dust- and weather-resistant design* for a wide range of outdoor scenes, enabling mobile shooting. Capture those rare, unexpected shutter opportunities, regardless of weather, while protecting your precious lens from water droplets and dust. *When mounted on a Panasonic dust- and weather-resistant camera body. Low-temperature resistance down to -10°C. Captivating in cold regions like snowy mountains and slopes, the camera is designed to withstand temperatures as low as -10°C. Capture the beautiful, fantastical world of snow and ice as new photographs. "S" red emblem. A robust, high-quality design that fits comfortably in your hand and inspires your photography. The form feels as comfortable in your hand as a familiar tool. Graphic lines express the path of light from the lens to the viewfinder. Unique vertical slit knurling balances operability, ease of maintenance, and aesthetic appeal. The glossy black surface finish, common to the S series bodies, is a testament to the camera's unique design. The "S" emblem subtly asserts that this is a sturdy, no-nonsense product that prioritizes mobility and usability. The graceful body lines and high-quality texture will inspire you to take photos and bring you the joy of owning it.
