(From Panasonic lens literature) Panasonic has unveiled a new pancake interchangeable lens called the LUMIX G 20mm ƒ/1.7 ASPH. (35mm camera equivalent: 40mm) as a new member of the LUMIX G Micro System. The new LUMIX G 20mm ƒ/1.7 ASPH. features a dramatic compactness and light weight despite its ƒ/1.7 brightness allowing a beautiful soft focus for photos to be even more impressive.
Comprising of seven lenses in 5 groups, the new lens system uses two aspherical lenses most effectively to minimize both distortion and chromatic aberrations, achieving super high resolution corner to corner. The versatile 20mm of focal distance (equivalent to 40mm on a 35mm film camera) is suitable for wide variety of occasions from daily snapshots including sceneries like sunsets and dimly lit indoor shots to the deliberately creative shots taking advantage of its beautiful soft focus. When mounted on the LUMIX G Micro System Cameras, the LUMIX G 20mm ƒ/1.7 ASPH. allows use of the advanced contrast AF system, which includes a Face Recognition function, for more convenient, more enjoyable shooting.
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. The new LUMIX G 20mm ƒ/1.7 ASPH. lens also features a highly reliable metal mount, and uses multi-coated lens elements that minimize ghosts and flare to further enhance its optical performance.
