The LUMIX G 20 mm / F1.7 ASPH features a dramatic compactness and light weight despite its F1.7 brightness allowing a beautiful soft focus for photos to be even more impressive. The versatile 20 mm of focal distance (Equivalent to 40 mm on a 35 mm film camera) is suitable for wide variety of occasions, from daily snapshots including scenery like sunsets and dimly lit indoor shots to the deliberately creative shots taking advantage of its beautiful soft focus. When the lens is mounted on the LUMIX G Micro System Cameras, the LUMIX G 20 mm / F1.7 ASPH allows use of the advanced contrast AF system, which includes a Face Recognition function, for more convenient, more enjoyable shooting. The LUMIX G 20mm / F1.7 ASPH utilizes a lens drive system to realize a compact and bright F1.7 lens. As a result, sound and vibration may occur during focus operation, but this is not a malfunction.
