Panasonic Leica 10-25mm f1.7 DG Vario-Summilux Lens


The Panasonic Leica 10-25mm f1.7 DG Vario-Summilux Lens is built for mirrorless cameras mount: Micro Four Thirds, and enables full range f1.7 aperture brightness within the entire 20-50mm (35mm camera equivalent) zoom range. Along with an exceptionally high optical performance clearing the LEICA standards. Applicable for photo shooting as well as recording video. Satisfying both photographers and videographers.

With 17 elements in 12 groups, featuring three aspherical lenses and four Extra-low Dispersion lenses within the lens system effectively suppress chromatic aberration of magnification and axial chromatic aberration. For stunning resolution, the aspherical lenses also correct spherical aberration and distortion. Despite its outstanding optical performance lens system, as well as the use of aspherical lenses, the lens results in a lightweight compact size.

Compatible with a max 240-fps high-speed sensor drive realizes high-speed, with high-precision autofocusing. The Panasonic Leica 10-25mm lens excels in video recording performance. Silent operation is achieved by the inner focus drive system, in addition, the step less “de-clicked” micro-step drive system and aperture ring in the aperture control section help for the camera to easily correct to brightness changes while panning or zooming. This new optical design achieves exceptional barycentric stability that helps to minimize image shifts while in zoom. The focus clutch mechanism enables for instant AF/MF changing and accurate manual focusing. The Panasonic Leica 10-25mm f1.7 also excels in video recording performance. Suppression of focus breathing is enabled with a mechanism. Ultimately resolving the problem of all interchangeable lenses that are designed for still photography.


  •  Leica Camera AG's quality standards optimized for photo/video have been developed into the hard-wearing mirrorless Micro Four Thirds mount lens.
  •  Full range F1.7 full range – High-speed aperture brightness of F.17 across entire zoom range 10-25mm 
  • Stepless Aperture – Stepless “de-clicked” aperture ring and micro-step drive aperture system provide a smooth transition with rapid changes in scene brightness.
  • Reduced Brightness Shifts - To minimize image shift during zoom, the optical design achieves exceptional barycentric stability.
  • Clutch Focus –The focus clutch mechanism enables instant AF/MF switching with accurate manual focusing including an inner focus drive system that provides nearly silent operation.
  • The rugged design provides a dust/freeze/splash resistance that can withstand harsh conditions.

*Dust and Splash Resistant will not guarantee that damage will not occur if the lens is subjected to direct contact with water and dust.

Notices and Disclaimers: Splash Resistant* / Dust Resistant: Splash Resistant is a term used to describe an extra level of protection against exposure to a minimal amount of water, moisture, or dust. The Splash Resistance does not guarantee that damage will not occur if the device is in direct contact with water. Minimizing Damage: To minimize the possibility of damage, please be sure the following precautions are taken: (1) The Splash Resistant feature is only compatible with cameras, lenses, and accessories that carry the same Panasonic Splash Resistant certification. (2) The device is not designed to be Dust and Splash Resistant when a USB connection cable or cable holder is attached. (3) Be sure that all doors, caps, sockets, and terminal covers are securely closed. (4) When changing the battery, lens, memory card, or other accessories, be sure that you are in a secure and dry place. After changing, make sure protective doors are secure and closed. (5) If the device is exposed to foreign material like water, or sand, make sure to clean it as soon as possible! Take the necessary precautions so the foreign substance does not get inside the device. Camera Monitor Cleaning: If sand, dust, or liquids such as water droplets stick to the monitor, wipe it off with a dry soft cloth. (6) If you do not do this it may cause the monitor to respond incorrectly to touch operations. (7) If the monitor is closed when liquids are present, a malfunction may result. Cold Temperatures: When using in cold temperatures (10C to 0C (14 F to 32 F): Please attach a Panasonic interchangeable lens with the minimum recommended operating temperature of 10 C (14 F) before use. Caution: Use caution, do not place your hands inside the camera mount of the digital camera body. The sensor unit is a precision apparatus, doing so may cause damage or a malfunction to occur.
