Panasonic has announced the Lumix G 20mm F1.7 II ASPH, a revised version of its classic fast pancake lens for Micro Four Thirds. The H-HS020A, as Panasonic likes to call it, features a metallic exterior and slightly reduced weight, and will come in a choice of silver or black finishes. The optical design appears to be unchanged, with 7 elements in 5 groups including 2 aspheric elements; not a bad thing as its predecessor is one of our favourite lenses. The 20mm F1.7 II will be available in late July at a price of $399/£349.

Panasonic Announces LUMIX G 20 mm / F1.7 II ASPH - Fast Single Focal Length Digital Interchangeable Lens in Sophisticated Exterior Design

Panasonic is pleased to announce the addition of a new single focal length lens LUMIX G 20 mm / F1.7 II ASPH. (H-H020A). Joining Panasonic’s well regarded family of digital interchangeable lenses of LUMIX G based on the Micro Four Thirds standard, this model features a newly designed metallic profile, and sleek, sophisticated design elegantly finished in black and silver. Maintaining the stunning performance of LUMIX G 20 mm / F1.7 ASPH., the new LUMIX G 20 mm / F1.7 II ASPH. is extremely compact and lightweight & its F1.7 brightness that enables beautiful soft focus on the background for the subject to stand out impressively.

Comprising seven lenses in five groups, the new lens system uses two aspherical lenses effectively to minimize both distortion and chromatic aberrations, achieving super high resolution from corner to corner. The versatile 20 mm focal distance (equivalent to 40 mm on a 35 mm film camera) is suitable for a wide variety of occasions from daily snapshots, to beautiful sceneries like sunsets, and dimly lit indoor shots taking advantage of its beautiful soft focus. The new lens supports Contrast AF system for high precision auto focusing.

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 20 mm / F1.7 II 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. The new addition will be available from 29th July 2013.
