The LUMIX G 20mm/F1.7 II ASPH, is a compact and lightweight "pancake" lens with outstanding brightness. Featuring a new metallic profile in the Micro Four Thirds standard.

It supports the Contrast AF system for high precision auto focusing.

Seven blades give the aperture a rounded shape that produces an attractively smooth effect in unsharp areas when shooting at large aperture settings. The new LUMIX G 20mm / 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.

Great Walkabout lens


from Hong Kong  -  Hobbyist/Enthusiast

This is a really sharp lens, and it's small, so it's very unobtrusive. This makes it great for street photography. In 35mm terms, it's a 40mm lens, which is very close to being 'normal' i.e. mimicking the normal field of view. If you like the 35mm focal length, you'll feel right at home with this. Excellent in low light and indoors.

Great lens


from Seattle, WA  -  Hobbyist/Enthusiast

Still learning the coolness of this lens other than it is SHARP! Only a week into my GF6 camera so still learning all of the great features. This is my go-to lens now. Spectacular low-light performance. Only gripe is the noise when focusing. It also doesnt auto focus as quick as the default 14-42mm lens that comes with the GF6. Other than that a great lens. I love the 20mm! This is the newer one with the full aluminum mount so a little heavier than the old version.
