Product description
Announced Sep 2, 2009

The Lumix G 20mm F1.7 ASPH is a tiny 'pancake' lens for Micro Four Thirds cameras, which offers a ‘normal’ 40mm-equivalent angle of view and a fast F1.7 maximum aperture. Optically it’s very good indeed, even at maximum aperture. However autofocus is relatively slow compared to more-recent internal focus lenses such as the Panasonic 25mm F1.4. Despite this the 20mm is still one of our favorite lenses, due to its winning combination of small size, high all-round image quality and excellent low-light capability.

Our review

The 20mm F1.7 is an excellent lens, especially considering its tiny size. It does well in all aspects of our studio tests, and produces fine images in a wide range of situations while also focusing quickly, silently and decisively. On compact Micro Four Thirds bodies it offers impressive image quality and low-light capability in a package significantly smaller and more discreet than any DSLR system.

Good for: Everyday use on compact Micro Four Thirds bodies, where is small size and excellent optical performance make an appealing package

Not so good for: It's not the most versatile lens in the world, but overall there's little to criticize.
