The Sigma DP2 [official site], which uses a full-sized DSLR sensor and a fixed-focus lens in a point-and-shoot body, is about to be dumped on the world. An update to the somewhat awkward DP1, the DP2 moves to a "brighter, tighter" f/2.8 41mm lens, as well as a host of other minor tweaks that hopefully will make it a better choice for the average user. No price has yet been announced, but expect it to be in the high hundreds. Wired mag has an infographic about the design that went into the DP1 in the current issue. Apparently the entire metal front of the camera acts as a heat sink for the "Trisket-sized" sensor.
