For Sigma, the latest Photokina has been an important event. Not only for them being a lens manufacturer but also a camera manufacturer. At that time Sigma introduced the Sigma SD14, a digital SLR camera based on the deviated Foveon X3 image sensor. Besides that Sigma introduced the DP1 digital compact camera that has been equipped with the Foveon image sensor. Not one of these cameras had reached the final stage then and the availability of the Sigma SD14 was even postponed. But at the PMA 2007 Sigma announced the availability of the Sigma SD14 digital SLR and the first results are starting to appear here and there on a users forum and on different web sites of the true Sigma lovers.

Sigma DP1

• Category: Digital Cameras

Sigma announces the launch of the Sigma DP1 using three silicon embedded layers of photo sensors stacked to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths. The size of image sensor used in DP1 camera is approximately 10 times larger than those used in an ordinary point and shoot camera. Large size image sensor takes advantage of larger pixels. So far point and shoot digital cameras incorporated small size image sensors, and researches for increasing the number of pixels by keeping the image sensor small is still continuing. However, there are limitations in these researches, because keeping image sensor size small will result poor capture of the light poorly.
