Panasonic LUMIX G 20mm F1.7 ASPH. (H-H020) First Model [Product Features] This high-performance single-focus lens for Micro Four Thirds is attractive for its thinness (pancake type), making it convenient to carry, and its bright f/1.7 aperture. The first model, in particular, is still highly popular today for its unique rendering. It's ideal for portraits and snapshots because it can take beautiful photos with a large, blurred background.
