PMA 2009: Panasonic has today broadened the perspective of the Micro Four Thirds system with the announcement of the Lumix G Vario 7-14mm F4 ASPH ultra wide-angle zoom. This new lens takes full advantage of the short back focus distance of Micro Four Thirds to reduce the size and weight dramatically compared to similar lenses, to just 70mm x 83mm and a mere 300g. Two Aspherical elements and four Extraordinary Dispersion glass elements are used to reduce distortion and chromatic aberration, and a built-in petal-shaped lens hood protects against flare from stray light.

Featuring Ultra Wide Angle in Compact Size
March 3, 2009: Panasonic today unveiled a new interchangeable ultra wide-angle zoom lens called the LUMIX G VARIO 7-14mm/F4.0 ASPH. In spite of its impressive wide-angle zoom range of 7-14mm (35mm camera equivalent; 14-28mm), the new lens is surprisingly compact and lightweight for casual on-the-go use.
Taking advantage of its wide, 114-degree angle of view, users can easily fit subjects into the frame even when shooting indoors where the distance is limited. The world looks extraordinary when viewed through the new lens, allowing photos and movies to be recorded with a uniquely rich perspective.
This high-performance lens system achieves outstanding compactness by combining 16 lens elements in 12 groups, including two aspherical lenses and four ED lenses. Image resolution is high from corner-to-corner even at the wide-angle setting. It also features F4.0 brightness over the entire zoom range thanks to its large-diameter glass moulded lens elements.
When mounted on the DMC-GH1 Lumix G Micro System Camera, the new lens 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 LUMIX G VARIO 7-14mm/F4.0 ASPH lens also features a highly reliable metal mount, and uses multi-coated lens elements that minimise ghosts and flare to further enhance its optical performance. The optimally designed lens hood enables use even under strong sunlight.
