4.5

The Panasonic Lumix G 20mm F1.7 ASPH was announced earlier this month as the natural companion to the compact Lumix DMC-GF1 Micro Four Thirds camera, alongside a Leica-branded 45mm F2.8 Macro (the camera is also available with a 14-45mm kit zoom). The H-H020, as Panasonic curiously likes to call it, is a large maximum aperture 'normal' prime in a very compact 'pancake'-type body. It gathers a stop and a half more light than Olympus's M. Zuiko Digital 17mm F2.8 pancake (which is only marginally smaller), and is therefore sure to be of interest to E-P1 owners who want to shoot in low light using a lens well-matched to that camera's size.

The Panasonic Lumix G 20mm f/1.7 II ASPH Lens Review — Tools and Toys

Small, light, fast and with exceptional image quality, this pancake lens is a staple of the Micro Four Thirds system. An optical jewel worthy of a place in every camera bag, regardless of experience.
