Reinvention of camera, reinvention of DP
SIGMA dp2 Quattro
Sigma Imaging (UK) Ltd is pleased to announce that the dp2 Quattro will be available in early July with a suggested retail price of £899.99 including VAT.
Unique and without peer among image sensors, the Foveon direct image sensor is similar to traditional color film in that its multiple layers capture all of the information that visible light transmits. Along with Sigma’s proprietary image processing technology, this sensor produces incredible resolution, precise gradation, gorgeous color, breathtaking realism with a 3D feel. In other words, full-bodied image quality.
For the new dp series, we rethought and redesigned every aspect of the camera, including the sensor, engine, lens, and body. While retaining its famous textural expression, which seems to give form to the air itself, the updated Foveon direct image sensor produces images that are more colorful, rich, deep, and faithful than ever before.
To a radical degree, the new-generation dp series embodies Sigma’s philosophy of creating cameras that produce works of art. Featuring the highest level of fundamental performance, this series unites artistic expression and daily experience as no other cameras can.
With every element optimized for lens and sensor performance, this camera is simple yet powerful
To deliver full-bodied image quality with all of its rich and colorful detail, we rethought and optimized every element of the camera, including the ultra-high-resolution sensor, the top-performance lens, and every component involved in motion and operation. Unchanged from the first generation is a key element of the specification, the fixed focal length lens, which we selected as the optimal way to deliver the highest possible level of image quality.
The dp is able to process high volumes of image data at a level similar to that of a high-end DSLR, and the shape, weight, layout, and other camera elements all come together in a compact body to deliver outstanding image quality. In addition, the dp offers superior handling and highly intuitive operation. In sum, these features allow the photographer to concentrate fully on photography itself, leveraging the camera’s potential to produce outstanding images.
In everyday life, the dp series lets photographers find unexpected opportunities for experiencing emotion and enjoying photography and personal expression in exciting new ways. It is an outwardly simple yet extremely powerful embodiment of Sigma’s philosophy of photography.
The world’s only image capture system to use vertical color separation technology
Leveraging the light absorption characteristics of silicon, the 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.
The Foveon direct image sensor captures color vertically, recording hue, value, and chroma accurately and completely for each pixel, enabling the expression of rich gradation and tone. Moreover, there is no low-pass filter needed to correct the interference caused by a color filter array, unlike the data from other sensors, which requires artificial interpolation to “fill in” missing colors. The data from the Foveon direct image sensor is complete with light and color information for every single pixel.
Newly developed Foveon X3 Quattro direct image sensor
The SIGMA dp2 Quattro incorporates a newly developed Foveon X3 direct image sensor (generation name: “Quattro”). The new sensor structure features a pixel ratio of 1:1:4 from the bottom, middle to top layer. The Foveon X3 Quattro direct image sensor is able to detect a broad range of light wavelengths. While the top layer captures both brightness and color information, the middle and bottom layers with their larger surface area capture color information only. During the image data processing stage, the brightness data captured in the top layer is applied to the top, middle, and bottom layers, resulting in brightness and color data for each individual pixel.
Retaining the principle of the three-layer structure where colors are divided vertically, by applying the brightness data captured in the top layer to the layers below, high resolution and high-speed for broad data processing required are achieved.
Equivalent to 39 megapixel high resolution
A conventional color sensor captures resolution information through green megapixels, which means the information it can contain is only 50% of the whole pixels. On the other hand, the new Quattro sensor captures resolution information with the whole top layer. It holds twice as much resolution compared to conventional color sensors. 19.6 megapixel resolution information of the top layer achieves high resolution equivalent to 39 megapixels.
TRUE III image processing engine
The new dp series cameras feature the newly developed TRUE (Three-layer Responsive Ultimate Engine) III. This image processing engine has evolved in pace with our Foveon direct image sensor and incorporates all of the image processing expertise we have developed over the years. Thanks to new refinements, it is the ideal engine for processing the rich and complex image data produced by the new-generation Foveon X3 Quattro direct image sensor. Our proprietary algorithm makes possible ultrafast processing of an immense volume of image data without any deterioration of the final images. The result is high-definition, 3D-like photographs with outstandingly rich color detail.
High performance 30mm F2.8 lens
Based on our rigorous examination of lens options to match the new Foveon X3 Quattro direct image sensor, we’ve retained the same lens specification as in the DP2 Merrill; 30mm F2.8 (equivalent to a 45mm lens on a 35mm SLR). Building on the well-received approach we took with the previous-generation DP2 Merrill camera, we’ve incorporated a glass mold aspherical lens and three high refractive index glass elements so as to minimize every type of optical aberration. Extremely sharp and stable in performance, this camera gives you the power to capture even tiny subjects with high precision. Its image plane characteristics are also outstanding, featuring a consistently crisp focus and a smooth, natural gradation to the out-of-focus areas of the image.
A solid and lightweight magnesium alloy is incorporated to the part of exterior. With rigidity and strength, the body is highly reliable and superior as a tool for photography.
Quick Set Menu
The Quick Set (QS) Menu which consists of the 8 most commonly used functions such as ISO and White Balance can be easily displayed by pressing the QS button. Using the Selector, the Front Dial and the Rear Dial, change of the settings can be made in no time. It allows photographers to change the menu content and the order depending on their preferences.
The SIGMA dp2 Quattro features “9 point select mode” which can select the desires focusing point from 9 different frames and “Free move mode” which can move the desired point as you like. “Face Detection AF” prioritizes focus on the face of the subject when detected by the sensor. Moreover “AF Limit Mode” which adjusts the range of auto focusing and “Shutter Priority AF” which offers faster focus adjustment by stopping the live view can be selected to increase the speed of the auto focusing. By selecting “AF+MF mode”, the focus can be adjusted manually after verifying the AF by rotating the focus ring. The SIGMA dp2 Quattro has an AF auxiliary light inside, which enables auto focus shooting in a low light environment.
Manual Focus is available for use when autofocus or focus lock is not desired. It is possible to use the focus ring for focusing just like an SLR camera. It is also possible to magnify the display to ensure precise focusing.
14-bit RAW data
RAW data records information of light captured by the Quattro sensor. 14-bit (16384 tones) signal processing is incorporated when the analog output signal is transformed to a digital signal, achieving photography data with excellent tones and smooth gradation of subjects.
RAW data incorporates lossless compression that prevents data from degradation. By processing images using SIGMA Photo Pro, it is possible to create images with natural balance like no other.
SUPER HIGH size with 39 megapixel high resolution
The SIGMA dp2 Quattro has High size and Low size to select from depending on the purpose of the photography. High size gets the best performance out of the image sensor both with RAW data and JPEG and Low size focuses more on the number of images that can be recorded. With both of the sizes, simultaneous recording of RAW and JPEG is possible. Moreover, for JPEG, SUPER HIGH that is suitable for larger prints can be selected to accommodate photographers’ various needs.
Capable of 7 frames continuous shooting
A large volume buffer memory enables the camera to capture up to 7 RAW images per sequence in continuous shooting mode in High size. Using high speed data transfer and processing, the SIGMA dp2 Quattro features a continuous shooting speed of up to 3.5 frames per second. In addition, depending on the situation, it is possible to capture up to 4.5 frames per second and up to 14 images per sequence in continuous shooting mode in Low size.
The aspect ratio of 3:2 is set as standard however 5 different aspect ratios are available including 1:1 and 21:9, similar to those of wide screens used in cinemas, depending on your photography needs. Images recorded as RAW format can be changed to different ratios in SIGMA Photo Pro.
An electric level that is useful in determining composition can be displayed. The camera’s horizontal and vertical directions are displayed while shooting.
10 White Balance options
In addition to the Auto (Default) option that allows the camera to automatically determine the appropriate white balance adjustments, Auto (Lighting Source Priority) option is incorporated. This option allows the camera to adjust white balance while valuing the color and atmosphere of light source. 10 options are available and it is also possible to adjust white balance based on the image incorporated, and to set the amount of color temperature (Kelvin). Moreover, each white balance mode can be fine-tuned, enabling detailed correction of white balance and creative work with a filter effect.
More preset Color Mode options
Color Mode can adjust rendering and contrast to best suit each photography scene. With the dp2 Quattro, 4 preset Color Modes are added including “Cinema”, which reduces saturation and emphasizes shadows to recreate an image like in a cinema and “Sunset Red” which emphasizes red color rendering, and expresses the scenes, such as sunsets, more impressively. True artistic expression has become easier than ever.
Advanced Monochrome options
With Filtering Effect contrast can be changed as if the images are taken using a color filter for black and white photography, and with Toning Effect color tones can be adjusted according to preferences such as WARM, COLD and SEPIA, so that photographers can create more impressive image of subjects.
Blown-out highlights caused by overexposure can be corrected, based on the gradation information obtained through the arrangement of pixels on the sensor, to minimize loss of detail.
ISO Sensitivity can be set by 1/3 Step
ISO sensitivity can be set from ISO 100 to ISO 6400. By setting the range to 1/3 EV steps from the default 1 EV steps, it is possible to set the sensitivity to ISO 125 or ISO 160. ISO AUTO, where the camera automatically sets the ISO sensitivity according to brightness of the shooting environment, enables you to set the upper limit and lower limit depending on your shooting style.
Exclusive Sigma Photo Pro software
SIGMA Photo Pro software makes possible to process RAW data instinctively. With an easy operation like moving sliders left and right while looking at the photographed image, your desired expression can be achieved. By changing modes, this software helps produce the stunning tones and gradation for which the Foveon X3 Quattro sensor is famed. In addition, the software also makes possible monochrome photographs of impressive depth.
The SIGMA dp2 Quattro adopts the SD Card (SDXC, UHS-I compatible) which is compact and easy to carry.
Large, highly visible 3.0” TFT color LCD Monitor
The SIGMA dp2 Quattro features a 3.0 inch TFT color monitor which ensures great visibility even outside in the daytime. This approximately 920,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to capture detail and to check focusing and composition.
The SIGMA dp2 Quattro is equipped with a hot shoe, allowing use of the dedicated external flashgun EF-140 S (optional) as well as SIGMA electronic flashguns for SD series such as EF-610 DG Super (optional) and EF-610 DG ST (optional).
Dedicated Cable Release
The dedicated cable release (CR-31) (optional) allows release of the shutter without touching the camera by connecting it to the camera’s USB terminal. It is useful when releasing the shutter from a distance or with a slow shutter speed, as well as to prevent image blur.
Dedicated lens hood
The dedicated bayonet lens hood (LH4-01) can be attached to block out extraneous light. Attaching Sigma’s optional dedicated 58mm DG filters such as the DG wide circular PL to the camera body extends the shooting possibilities.
* Lens hood and 58mm filters are sold separately.
