Sigma has announced that they have acquired the interesting image sensor producer Foveon. This will make Sigma able to produce new image sensors and thus new cameras. Foveon makes some really interesting sensors for cameras so I am looking forward to see how Sigma will implement their technology. I wish both companies best of luck.

Press release:
Kawasaki, Japan, November 11th, 2008 – Sigma Corporation (Location: Kawasaki, Japan) has acquired 100% of the stock of the company that developed the original three-layer image sensor, Foveon Inc. Foveon will continue its sensor development operations in San Jose, CA, USA.

Foveon made history when it developed and patented the world’s first three-layer image capture technology, placing a stack of RGB pixels in each pixel location. As a result, Foveon sensors detect all three primary colors in every pixel location, producing images that are sharper and have significantly reduced image artifacts compared to competing image sensor technologies.

Since Sigma first worked with Foveon in 2000, both companies have enjoyed a cooperative working relationship directed toward developing highly-efficient DSLR (Digital Single Lens Reflex) cameras and compact digital cameras which take the best advantage of the X3 sensor technology. Sigma Corporation has employed Foveon’s technology in its entire digital camera line, producing images which are acclaimed by both amateur and professional photographers all over the world for their high resolution and for their three-dimensional look. Both the latest DLSR, the SD14, and the compact DP1 camera – which packs the full spec of a DSLR into a compact camera – have met with similar acclaim. Two additional Sigma camera products based on Foveon’s image sensor technology have been announced for 2009.

The acquisition of Foveon will not only enhance the development of new types of image sensors for high quality digital cameras, but will also create a synergistic effect with Sigma’s camera and lens business by improving the integration between the camera and sensor. This will result in camera products which will uniquely meet the widely ranging functional and image quality needs of demanding photographers.

As the digital camera market continues to expand, Foveon and Sigma will continuously evolve and improve the X3 sensor technology, thus expanding the company’s photography-related business. In addition, Sigma remains firmly committed to preserving and nurturing the culture of photography.

Sigma has announced that they are releasing an improved version of their SD14 DSLR camera. The new Sigma SD15 DSLR features improved image processing and a larger 3″ LCD screen. It also has a 14 megapixel sensor that should please most people.
There is not much else new with the SD15 so Sigma fans might be a bit disappointed with this DSLR release?

Press release:
Sigma Corporation is pleased to announce the new Sigma SD15, a 14 megapixel (2,652×1,768×3 layers) Digital SLR camera.

This camera is the latest model in Sigma’s digital SLR camera SD series, powered by the 14 megapixel Foveon X3 direct-image-sensor it can capture all primary RGB colors at each and every pixel location arranged in three layers.

The developing SD15 incorporates the “TRUE II” new image processing engine. It provides high resolution power and reproduces high definition images rich in gradation and impressive three-dimensional detail. Incorporation of the large 3.0 inch LCD monitor and improved processing speed provide ease of operation of the camera.

Development of the SD15
Since October 2002, Sigma has introduced three digital SLR cameras, the SD9, SD10 and SD14 to the market. In March 2008 Sigma also introduced a high-end compact digital camera, the DP1 which uses the same large image sensor as is featured in Sigma’s digital SLR cameras. They have established a strong following from a wide range of photographers, both amateur and professional. Photographers expressed a desire to incorporate the image processing engine “TRUE”, which is used in the DP1, into a digital SLR camera. In order to meet this demand, the SD15, with high resolution direct image sensor, has been designed around the new “TRUE II” image processing engine. This combination delivers superior image quality as well as improved processing speed, operation and performance.
