SIGMA sd Quattro/SIGMA sd Quattro H

The SIGMA Corporation is pleased to announce the SIGMA sd Quattro and SIGMA sd Quattro H, two new high-image-quality digital cameras that incorporate the Foveon X3 direct image sensor (generation name: “Quattro”).

Building on the concept of the SIGMA SD1 Merrill, the SIGMA sd Quattro and SIGMA sd Quattro H feature a mirrorless structure and use interchangeable lenses. The two new cameras are as compact and lightweight as cameras in the SIGMA dp Quattro series and offer the same level of outstanding image quality. Featuring the SIGMA SA mount, the two new cameras are compatible with all of the SIGMA GLOBAL VISION lenses in the Contemporary, Art and Sports lines, and they are designed to take full advantage of these lenses’ superb optical performance.

The SIGMA sd Quattro features an APS-C size sensor and offers medium-format image quality with 39 megapixels. The SIGMA sd Quattro H features an APS-H size sensor measuring 26.6 x 17.9mm. This new, larger Foveon sensor delivers high resolution of 51 megapixels, for even more detailed expressive power.

Foveon X3 Quattro direct image sensor

Leveraging the light absorption characteristics of silicon, the Foveon X3 Quattro direct image sensor comprises three layers of photodiodes, each at a different depth within the silicon and each corresponding to a different RGB color. Since it is the only sensor to use this superior vertical color separation technology, it is also the world’s only direct image sensor. Requiring no low-pass filter needed to correct the interference caused by a color filter array, the Foveon X3 Quattro direct image sensor is able to take full advantage of the information carried by light, including color information. The sensor features a pixel ratio of 1:1:4 in the bottom, middle, and top layers and applies the brightness data captured by the top layer to the middle and bottom layers. This unique structure makes possible fast resolution and high-speed data processing.

Two sensor sizes available

Other cameras typically use a single-layer photo sensor covered by a Bayer filter mosaic, which comprises 50% green, 25% blue, and 25% red squares. In contrast, the Foveon X3 Quattro direct image sensor uses no low-pass filter and is able to capture 100% of the data for blue, green, and red in each of its three layers. Due to this unique structure, the Foveon X3 Quattro direct image sensor can generate up to twice the resolution data of sensors using a Bayer filter. The SIGMA sd Quattro has an APS-C-size sensor with 19.6 megapixels in its top layer, giving it an equivalent total of approximately 39 megapixels and the outstanding image quality expected of a medium format camera. The SIGMA sd Quattro H features a newly developed APS-H-size sensor (26.6 x 17.9mm) with 25.5 megapixels in its top layer for an equivalent total of approximately 51 megapixels. This larger sensor takes Foveon image quality to the next level, delivering more detailed images than ever before.

Dual TRUE III for high-speed processing of high-volume data

TRUE (Three-layer Responsive Ultimate Engine) III is the dedicated image processing engine for the Foveon X3 Quattro direct image sensor. SIGMA’s original algorithm processes data without loss of color detail or other image degeneration to deliver extremely detailed image expression with a noticeable 3D pop. In addition, by using two separate TRUE III engines, the camera is able to process data from the Foveon X3 Quattro direct image sensor at extremely high speed.

New Super-Fine Detail exposure mode

The new Super-Fine Detail (SFD) exposure mode brings out the full performance of the Foveon X3 Quattro direct image sensor. One push of the shutter generates seven different exposures, creating RAW data in the X3I file format. Using this data with the SIGMA Photo Pro software package, the photographer can create noiseless images with an extensive dynamic range. With this new mode, the more detailed imaging potential of the Foveon X3 Quattro direct image sensor is fully leveraged. From each X3I file, individual X3F files may also be generated. The value of SFD exposure mode is especially apparent in studio photography.

Press Release:

In developing any product, SIGMA always has a primary objective in mind: fundamental performance that gives everyone the opportunity to take the perfect photograph. Offering breathtaking resolution, rich gradations and colors, and exceptional realism, the Foveon X3 Quattro direct image sensor is a symbol of this never-ending pursuit of excellence. It delivers image quality so distinctively intense that even the temperature, humidity, and scent of a scene seem to impress themselves upon the viewer.

Presenting the ultimate digital camera experience, the new SIGMA sd Quattro series leverages the image quality of the Foveon X3 Quattro direct image sensor to build a complete system compatible with all SIGMA GLOBAL VISION high-performance interchangeable lenses. The sd Quattro series allows photographers to express themselves with even more freedom and precision.

Believing that the lens is the key to the photograph, SIGMA has created a new camera for the true photographic artist that leverages the power of high-quality lenses. Test its performance with your own hands and eyes—and be amazed.
