Sigma has announced that its dp1 Quattro large-sensor compact will be available from mid-October. It has also announced the LVF-01 magnifying loupe for the camera to allow the rear LCD to be used as an electronic viewfinder. The dp1 Quattro marries a 28mm equivalent F2.8 lens to the latest generation of Sigma's Foveon technology.
The Quattro's chip detects color by detecting how much light has penetrated to three different depths in the sensor. Unlike previous generations of sensor, the Quattro samples its top layer at 19.6MP, but only 4.9MP at the two deeper levels, using the top layer for resolution and blue capture and deriving the red and green information from the lower-pixel-count layers.
The dp1 Quattro joins the 45mm equivalent dp2 Quattro in the company's lineup, with the promise of a 75mm equivalent dp3 Quattro to follow. No pricing is given for the dp1 Quattro at the time of announcement.

Sigma Corporation of America Announces Availability of dp1 Quattro Camera, New Quattro Series View Finder
Widest of the high-powered, compact trio on shelves in mid-October, new accessory available in December
RONKONKOMA, N.Y. — September 12, 2014 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, today announced the availability of the Sigma dp1 Quattro camera and a new view finder that will magnify Quattro cameras' LCD screens. The second compact camera in the dp Quattro series will be available in the United States in mid-October and the accessory will be sold separately beginning in December. The pricing of both products has not yet been announced.
The dp1 Quattro utilizes a newly developed, fixed 19mm F2.8 wide-angle lens, equivalent to a 28mm on a 35mm camera, that is specifically designed and optimized to pair with Sigma's new Quattro sensor, making it the widest of the dp Quattro trio of cameras. One FLD glass element paired with two glass mold aspherical lenses minimize aberration. An optimized telecentric design improves image quality throughout the frame to maximize the resolution power of the Foveon senor. The dp2 (30mm) is currently available and the dp3's pricing and availability has yet to be announced.
In addition to the availability of the dp Quattro camera, Sigma has also announced a new LCD View Finder LVF-01, which is exclusively designed for the Quattro series of cameras. The LVF-01 attaches to the camera's LCD display to eliminate outside light and features a diopter adjustment range from -2 to +1. Coupled with the camera's high-performance lens and coating, it magnifies the LCD display 2.5 times, allowing photographers to check the focus more easily with enhanced clarity and visibility. The easy handling of the viewfinder also helps reduce camera shake.
As with all the cameras in the Quattro series, the dp1 Quattro boasts a redesigned camera body that enables optimal lens and sensor performance and it contains the newly developed Foveon "Quattro" Direct Image sensor, which is the only of its kind.
The Quattro sensor is a three-layered, panchromatic silicon chip whose green-sensitive middle and red-sensitive bottom layers each have 4.9 MP and record only color/chrominance information. The top blue layer captures chrominance and resolution/luminance information with 19.6 MP, resulting in greater detail capture and resolution capabilities that are higher than the Merrill DP camera line. The Quattro sensor's architecture also contributes to true color rendition and more detail capture, delivering even more realistic images as well as faster image processing, improving overall user experience.
"We value image quality above all else and the engineering, craftsmanship and functional design of the Quattro cameras produce emotive imagery with the richest tones, gradations and textures," said Mark Amir-Hamzeh, president of Sigma Corporation of America. "Our Sigma users are particularly enamored with the wide, 19mm lens in the dp1, which has been redesigned to maximize the capabilities of the Quattro sensor."
The dp1 Quattro camera will differ from earlier generations of the DP cameras, as it will feature:
- Foveon direct image sensor that produces images that are more colorful, rich, deep and faithful than ever before
- Improved battery life
- Fixed focal length cameras, providing the most optimized combination for unmatched image quality.
- The TRUE III Image processor, providing ultrafast processing of an immense volume of image data without any deterioration of the final image
- Better high ISO performance with one to two stops of improvement
- Improved 3A performance: Auto Exposure, Auto Focus and Auto White Balance
- Enhanced Standard, Vivid, Neutral, Portrait, Landscape, FOV Classic Blue, and Monochrome color modes, and new Cinema, Sunset Red, Forest Green, and FOV Classic Yellow color modes
