Sigma DP1

Sigma DP1

The Sigma DP1 is a high-end compact digital camera introduced by the Sigma Corporation. It features a 14-megapixel Foveon X3 sensor (2652 × 1768 × 3 layers), a fixed 16.6 mm F4.0 lens (28mm equivalent), a 2.5” LCD and a pop-up flash. It was the first "compact" camera that featured an APS-C sized sensor, a feature that Sigma claimed would result in DSLR quality images from a small, pocketable camera.

Front of the Sigma DP1

It was first announced on September 26, 2006, and after several production delays was delivered in the spring of 2008.[1] A follow-up camera, the Sigma DP2, was released in 2009; it features a different lens, and they are being sold in parallel.An improved version called DP1S was announced on November 17, 2009.[2]



It has been praised for innovation (large sensor in compact body) and class-leading detail at ISO 100 – best image quality in a compact camera, in the same class as DSLRs, and suited for daylight landscape and architecture photography – but criticized for poor low-light performance and slow speed, summarized as "a great concept that needs a considerable amount of additional work".[3] The user interface has also been criticized.[4]
