有dual I.S.
The key features of the newly developed cameras, the LUMIX S1R and the S1, are as follows.
1. Capabilities with high definition and high level of expression achieved with the newly-developed 35 mm full-frame image sensor and image processing engine.
(Effective pixels: approximately 47M for the S1R and 24M for the S1)
2. World’s first support for 4K 60p video recording in a full-frame Digital Single Lens Mirrorless camera.
3. World’s first full-frame camera equipped with Dual I.S. (Image Stabilization), enabling handheld shots for dark or distant scenes that would previously have required a tripod or other equipment.
4. A double slot for XQD memory cards and SD memory cards, the first for Panasonic; and a rugged triaxial tilt LCD, emphasizing ease of use and supporting professional photography and videography.
5. Leica Camera’s L-Mount, making it possible to use interchangeable lenses that meet the L-Mount specifications of the partners Leica Camera and Sigma. Expressiveness is further enhanced by increasing options for interchangeable lenses.
