The Lumix DMC-LX7 Digital Camera (Black) by Panasonic brings with it a fully redesigned lens, sensor and image processor for fast performance and gorgeous picture quality. Starting with the newly developed 24mm Leica DC Vario-Summilux lens, we will see why the LX7 is a cut above the rest in terms of high quality optics in a point and shoot. The LX7's lens is a 3.8x optical zoom lens with a focal length equivalency of 24-90mm. That is a great standard zoom for all your day-to-day shooting but what makes the lens special is its f/1.4 aperture at the wide angle end and f/2.3 at the telephoto end. These are apertures in line with the best available SLR lenses and will provide you with enough light entering your camera to use high shutter speeds and capture sharp images with beautiful gradations even in low light settings.
