PMA 2007: Another Sigma product revealed at Photokina but confirmed today is the DP1 compact camera with an APS size sensor. The DP1 features the same Foveon 14M X3 sensor (2652 x 1768 x 3 layers) as the SD14 and a fixed 16.6 mm F4.0 lens (providing a 28 mm equiv. FOV). Significant changes since the development announcement back in September include a hot-shoe and external viewfinder.
