As a current Sigma SD10 user, as well as having a Contax G2 and Voigt R2 with the Ultron 35, I visit the various Sigma forums as well. It appears that the specs for the DP1 are not entirely final. It probably will have the 28mm equiv. lens, but it could go to 35 and, after a lot of complaints, it looks like it may have an accessory shoe for a viewfinder, if not an OVF. Sigma got a lot of input on the camera from Sigma users after the prototype was shown. Based on the performance of the SD14, as noted in the Sigma forums by some testers of the SD14, the DP1 ought to be a match for the M8, image quality-wise, because it uses the SD14 chip. The SD14 sensor appears to perform better than most (all? No one knows, yet) 8-10MP Bayer sensors. The slow 28mm lens equiv was chosen to keep the lens from getting too big on the camera. In addition, the Sigma/Foveon sensor produces excellent BW images. The camera is eagerly awaited, to say the least.
