Lens Description: Achieving f/1.7 high-speed aperture, the LUMIX G 25mm F1.7 ASPH. keeps its size compact and weight light. The large aperture allows a beautiful soft focus for photo and video to be even more impressive and encourages users to capture the subject without using a flash even in dimly-lit conditions. The new lens system is comprised of 8 elements in 7 groups featuring two aspherical lenses and an Ultra-High Refractive Index (UHR) Lens. It incorporates a superior inner focus system which enables excellent resolution and contrast from the closest focusing distance to infinity. The inclusion of a stepping motor makes the focusing action smooth and silent for use in both still and video recording. Seven blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings. A highly reliable metal mount assures durability for active use, and uses multi-coated lens elements that minimize ghosts and flare to further enhance its shooting performance.
