In an interview with the British publication Amateur Photographer, Sigma founder Michihiro Yamaki has revealed that his company is already working on successors to its yet-to-be-released DP1 compact camera (pictured right). Although no specifications have been published, the DP2 and DP3 are expected to be announced by the end of the year, and will presumably share in common the same sort of full-frame sensor that reduces noise while still increasing sensitivity. Most compacts and even DSLRs use cropped technology, which also artificially shifts the focal length of lenses.

Sigma is also said to be working on the SD15, an upgrade to its 14-megapixel SD14 DSLR. This will use the same image processor found in the DP1, and should be announced at the Photokina expo scheduled for this September. [via PhotographyBLOG]
