The Panasonic Leica DG Summilux 12mm f/1.4 ASPH Lens is a professional level wide angle prime lens for Micro Four Thirds digital cameras. It delivers exceptional optical performance while maintaining a compact form factor, perfect for the more discerning photographer who values flexibility and quality.

Wide Field of View

Designed for Micro Four Thirds, the lens offers a 24mm focal length in 35mm equivalent terms, allowing to you to fit a wider perspective of your subject in the frame. The 12mm focal length provides an 84° angle of view, making the lens ideal for a diverse range of photographic scenarios including landscape & street photography, architecture & interiors, and group & event photography.

Ideal for Low Light Shooting

A bright maximum f/1.4 aperture allows handheld shooting at high shutter speeds without requiring a flash unit. In addition, the large maximum aperture allows exceptionally shallow depth of field, allowing a clear definite separation of elements within your composition. The fast aperture combined with a high resolving capability assures outstanding night scenes to make the lens ideal for astrophotography and low light imagery.

Exceptional Leica Image Quality

The lens is made up of 15 lens elements in 12 groups, with each of the lens meeting strict Leica quality and performance standards. A pair of aspherical (ASPH) elements contributes to achieve the lens’s compact form factor and helps reduce weight while minimising distortions. One Extra-Low Dispersion (ED) and two Ultra Extra-Low Dispersion (UED) lenses correct chromatic aberration and edge flare to render sharp, high-contrast images with clear colours corner to corner even at wide apertures. The image quality is further enhanced with multi-coating on the lens elements to reduce ghosting and flaring making the lens capable of excellent optical performance.

Quiet High-Speed AF

A smooth and silent stepping motor ensures precise and high speed auto focus. The lens handles aperture changes very smoothly to eliminate jumps in exposure while the silent motor enhances capture of audio, making the lens suitable for video recording. The auto-focus is capable of keeping-up with precision autofocusing systems to ensures the capture of sharp in focus 4K video and stills.

Macro Shooting Capable

A closest focusing distance of 20cm and a maximum magnification of 0.1x gives the lens remarkable macro shooting capability enabling you to get closer to smaller subjects for creative effect.

Pleasing Bokeh Effect

Nine diaphragm blades contribute to form a circular aperture that creates gorgeous out-of-focus areas in the image, when shooting at large aperture settings.

Ergonomic Design

A manual aperture ring on the lens barrel allows modification of the aperture in 1/3 steps and produces distinctive clicks as you change the settings. The tactile metal ring features markings from f/1.4 to f/16 and has an automatic aperture control setting for aperture priority shooting. A wide, ribbed and well-damped manual focusing ring allows electronic manual focusing that can be engaged through a dedicated AF/MF switch.

Inner Focus Drive

The lens employs an inner focus drive system. The filter thread does not rotate on focus, ensuring consistent performance when combining the camera with of polarisers and graduated neutral density filters.

All-Metal Weather Resistant Construction

Full metal construction gives the lens an ability to withstand harsh and rugged field usage especially when paired with a splash/dust proof Lumix Camera. The metal mount assures durability and an accurate fit to the camera body while a rubber gasket around the mount ensures a weather-proof seal. A dust & splash proof design protects the lens against light showers and water splashes and complements its outdoor usage as a landscape and street photography lens.

Compact Form Factor

Despite a complex optical design, the lens maintains a small size, making it ideal for compact micro four third system cameras. The sophisticated appearance and style of the lens matches that of the Lumix G series cameras.

Combining the best optical elements with a compact, stylish design makes the Panasonic Leica DG Summilux 12 mm f/1.4 ASPH Lens the perfect companion for your Micro Four Thirds camera.
