Compact lens with large F1.7 aperture: perfect for every day shooting

Two aspherical lenses are perfectly configured to deliver enhanced performance in a compact system and when this thin, pancake lens is mounted on the camera, the Lumix G Micro System is easy to carry anywhere. Your inner photographer is always ready for the inspiration to be found in everyday life, passing landscapes, indoors in dim lighting, casual snapshots, or in creative shots using soft focusing.

Lenses manufactured with uncompromising devotion to high image quality

The production process for Lumix G and LEICA DG lenses is conducted in ‘clean rooms’ to rigorous environmental standards. Now acclaimed worldwide, our UA3P Ultra-Accurate 3D Profilometer, with its measurement accuracy of 1/10,000mm, gives objective numerical evaluations and detects flaring, colour coatings and the ‘feel’ of the focus ring.

An original lens-drive motor for high-precision high-speed contrast AF

Lumix G and Leica DG lenses incorporate a unique ‘stepping motor’ with a screw unit in the motor shaft that moves the focus lens directly, without relay gears or cams. Information transfers from lens to camera faster, making auto focus swift and accurate with reduced drive noise for better movie recording.

Aspherical lenses

These lenses prevent spherical and distortion aberrations, so higher magnification can be achieved with fewer lenses. Resulting in smaller size and weight, these lenses feature the high dimensional accuracy of Panasonic’s cutting-edge production technologies, including concave lenses that measure just 0.3mm at their thinnest part.
