A big move for Sigma, the company has purchased Foveon, Inc, which developed the Foveon sensor. The Foveon is a 3-layer sensor, which detects the three primary colors in each pixel. Expect more from the Foveon in Sigma’s cameras next year and the years to come. The full press release follows.

Sigma Corporation Acquires Three-layer Image Sensor Developer Foveon, Inc.
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.

This autofocus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital SLRs with APS-C size image sensor, it produces circular image within the frame. The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLD (Special Low Dispersion) glass, Super Multi Layer Coating and inner focusing system provides superior image quality. HSM ensures fast and quiet autofocusing and includes full-time manual focus.
This diagonal fisheye lens is designed for use with digital SLR cameras equipped with an APS-C size image sensor. It produces a diagonal angle of view of 180 degrees. The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion. This lens has a minimum focusing distance of 13.5cm/5.3inch, and maximum magnification 1:3.3. It allows subjects to be as close as 1.8cm/0.7inch from the lens’ front element. The exclusively designed integral hood and the Super Multi-Layer Coating minimize flare and ghosting and create superior image quality.
The Sigma Corporation is pleased to announce the new ELECTRONIC FLASH MACRO EM-140 DG for Sony and Pentax cameras.
The Sigma Corporation is pleased to announce the new APO TELE CONVERTER 1.4x EX DG and APO TELE CONVERTER 2x EX DG for Sony mount. The new tele converters are capable of maintaining the HSM function of such telephoto lenses as Sigma’s APO 70-200mm F2.8 II EX DG MACRO HSM and APO 50-150mm F2.8 II EX DC HSM whilst increasing the focal length by a factor of 1.4x or 2x. Of course, the HSM (Hyper Sonic Motor) AF compatibility depends on the capability of the Sony SLR camera to support this function and on the maximum F number of the attached lens. The Super Multi Layer Coating reduces flare and ghosting and the exclusive design maintains the master lens’ high level performance while extending its focal length. Compact and lightweight, these tele converters are a convenient way of increasing the focal length of HSM telephoto lenses.
