The LUMIX G 20mm f/1.7 II ASPH. Lens from Panasonic is an extremely compact, pancake-style prime lens in the Micro Four Thirds system. It is compatible with Panasonic LUMIX G digital cameras. The lens has a 35mm equivalent focal length of 40mm and a fast f/1.7 maximum aperture that offers great low-light performance. The 7-blade rounded aperture produces pleasing bokeh in the out-of-focus regions of images. Two aspherical elements minimize both distortion and chromatic aberration. The lens supports the Contrast AF system for high precision auto focusing.
