Sigma launches dp2 Quattro with vertical color separation sensor

02/10, 11:18am

Multi-layer sensor splits light bands for more accurate color representation

Sigma has unveiled the first of a trio of compact cameras with vertical color separation technology. The dp Quattro collection all use the Foveon X3 "Quattro" image sensor, one which uses three layers of photodiodes assigned to each RGB color, with the manufacturer claiming it allows the camera to capture the hue, value, and chroma for each pixel more accurately than the mosaic-style sensors used in other cameras.

Sigma adds Merrill suffix to 46MP cameras

Sigma on Wednesday both remade and added to its camera lineup. First off, the company's new CEO, Kazuto Yamaki, revealed that the high-end SD1 DSLR will be renamed to SD1 Merrill and get a very significant price drop, from $9,700 to $3,300. Yamaki said the reduction is due to the lower production costs of the 46-megapixel APS-C sensor, though no performance compromises have been made.

Sigma brings 15.4-megapixel SD1 DSLR to Photokina

09/22, 8:25am

Sigma SD1 keeps Foveon X3 sensor, 11-point AF

Japanís Sigma Corp. has today taken the covers off its flagship Sigma SD1 15.4 megapixel DSLR at Photokina. It adopts a lightweight, weather-proof, solid magnesium alloy body to house its 1.5X crop Foveon X3 sensor. The technology enables the camera to capture all primary RGB colors at each pixel location rather than use a Bayer filter and leads Sigma to make a questionable claim to a 46-megapixel sensor.

Sigma makes conservative updates at PMA

Sigma has kept itself in action at PMA by upgrading two models and reintroducing a third.

Sigma DP2 camera ships to the UK

Sigma DP2 in UK

Sigma on Thursday acted on its word and launched the long-delayed DP2 in the UK. The 14-megapixel camera is a cross between regular compacts and digital SLRs and continues to hinge on its FOVEON sensor, which is significantly larger than in point-and-shoots and helps produce more professional images, particularly in RAW mode. It also gets full manual controls and, since it was first shown last year, now has light sensitivity up to ISO 3,200 as well as a quick-access button for some of the more common camera settings.

On Tuesday at the PMA expo, Sigma has demonstrated the DP2 digital camera, a successor to the DP1. First seen back in September, the DP2 shares its 14-megapixel FOVEON X3 image sensor with the company's digital SLR, the SD14, which is much larger than the sensor in other digital cameras. Touted as a compact digital camera with most of the functionality of a DSLR, the DP2 also has an ISO sensitivity range that tops out at ISO 3,200.

Sigma developing DP1 successors

03/03, 4:15pm

Sigma DP2, DP3, SD15

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 firms up DP1 camera pricing

Sigma DP1 Pricing

Sigma today set pricing for its long-delayed DP1 high-end compact camera. Set to launch worldwide in the spring, the camera will now be priced in Sigma's UK home at a minimum £550 ($1,083) including tax for the standard version and £600 ($1,181) for a version that bundles a hot-shoe mounted digital viewfinder for photographers who prefer composing shots in a similar fashion to a digital SLR.

Sigma preps DP1 camera for spring launch

01/31, 9:20am

Sigma DP1 in Spring

Sigma at the PMA photo expo has committed to a release window for the DP1, its unusual crossover between compact cameras and digital SLRs. Now due sometime in spring, the final camera still maintains the 14-megapixel Foveon sensor that defines its shooting characteristics. The new three-layer silicon technology (also used in the SD14) captures each portion an RGB image in one pixel instead of three and allows the sensor to be several times larger than for other point-and-shoots this size; this provides both a major lift both to resolution as well as color response, Sigma says. The DP1 also comes with a custom-tailored 16.6mm f4 lens that can produce a shallow depth of field effect normally impossible with compact cameras.

Sigma DP1 resurfaces, nearing completion

11/30, 3:50pm

Sigma DP1 resurfaces

Sigma, best known as a maker of third-party lenses, has at last issued an explanation as to why its long-awaited DP1 camera has yet to go on sale. The compact was first revealed at Photokina 2006, and had actually reached the pre-beta stage by early this summer; testing revealed however that the image pipeline was badly optimized, reducing image quality in favor of speed. As such Sigma decided to completely re-engineer the pipeline, as well as other specifications. The revised camera has just recently entered alpha testing, and as such is still an unknown distance away from release.
