The Lumix L100 is a compact, pocket-sized camera with a fast built-in 24-75mm (35mm equivalent) lens, a 16MP Four Thirds sensor, and one of the highest-resolution electronic viewfinders available. The larger sensor means image quality that is vastly improved over small-sensor compact digital cameras. It also allows Panasonic to offer improved low-light performance. Big sensor, small camera The Lumix LX100 is the first Panasonic point-and-shoot camera to feature a larger Four Thirds sensor. It’s the same 16MP CMOS sensor that can be found in the Lumix GM5, also introduced today. When shooting in 4:3 aspect ratio, resolution is 12.8MP; users can also choose 3:2 and 16:9 aspect ratios. The top ISO is 25,600, unusual for a pocket-sized camera. The other big news is the Leica DC Vario Summilux lens, which at a wide aperture of f/1.7-2.8 and with Leica’s quality control, should produce excellent images for a camera of this size. The lens is constructed of 11 elements in eight groups with five a spherical lenses, including two ED lenses. A nine-diaphragm aperture ring is said to produce smooth bokeh with circular specular highlights. Panasonic says they have improved AF acquisition time to 0.14 seconds, using a new Depth from Defocus technology. According to Panasonic, this technology instantly calculates distance to subject by evaluating two separate images with different sharpness levels, and this computation speeds up AF. The camera also offers Eye Sensor AF, which activates autofocus the moment you look into the eye-level viewfinder. That viewfinder, at 2,764k dot resolution, is one of the high-test-resolution EVFs currently available. The camera also has a 3-inch, 921k-dot monitor. 4K Video For videographers, the LX100 offers 4K video capture at up to 30fps and 1080p Full HD video at up to 60p in AVCHD Progressive or MP4 format.
