SIGMA introduces new sd Quattro Camera with Foveon X3 Technology

Sigma Canada is pleased to announce the SIGMA sd Quattro new high-image-quality digital camera that incorporates the Foveon X3 direct image sensor (generation name: “Quattro”). Building on the concept of the SIGMA SD1 Merrill, the SIGMA sd Quattro features a mirrorless structure and uses interchangeable lenses. The camera is as compact and lightweight as cameras in the SIGMA dp Quattro series and offers the same level of outstanding image quality. Featuring the SIGMA SA mount, the new camera is compatible with all of the SIGMA GLOBAL VISION lenses in the Contemporary, Art and Sports lines, and it is 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 new Sigma sd Quattro (Model: SDQ) has a suggested retail price of $1,149.95 and is expected to be available in August. The sd Quattro will be available in a body-only configuration and as a kit with the SIGMA 30mm F1.4 DC HSM | Art (Model: SDQ30DCK) with a suggested retail price of $1,499.95. 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. High resolution 39 megapixels Foveon sensor 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. 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. Combination of two AF detection methods Phase detection AF is superior for speed performance, while contract detection AF is superior for focusing accuracy. Combining these two methods in a single system delivers AF that is fast and precise at the same time. In addition, this approach to autofocus takes full advantage of the characteristics of high-performance lenses. The Single AF mode is optimal for everyday photography, while the Continuous AF mode is optimal for focusing on a moving object. In the latter mode, pressing the shutter button halfway causes autofocus to operate continuously, while Movement Prediction AF operates at the same time for more accurate autofocusing. A variety of other AF modes are also available. 9-Point Selection AF mode allows the user to select among nine focus frames. Free Movement AF mode allows the user to select the focus frame with high precision. Face Detection AF mode detects human faces and prioritizes focusing on them. The AF assist light incorporated in the camera body makes possible the use of AF even in low-light conditions. Dual monitors In addition to the 1.62 mega-pixel 3.0 inch TFT LCD main monitor, the rear of the camera features a sub-monitor that displays the number of remaining shots on the SD card, shutter speed, aperture value, ISO level, and more. This extra monitor makes it easy to watch the live view and confirm key information at the same time. A sheet of special material lies between the two LCDs and the protective glass that covers them. This sheet prevents air pockets from forming and minimizes reflections, ensuring excellent display visibility in sunlight. HDMI port The MINI HDMI Type C port allows the user to connect the camera to an HD television with an HDMI cable (sold separately) and view photographs, camera menus, and even the viewfinder image in high definition on a big screen. USB 3.0 port The USB 3.0 Micro B port allows the user to connect the camera to a personal computer to download high-volume image files at high speed. Canadian Warranty The SIGMA sd Quattro has a one year Canadian warranty. Optional Accessories POWER GRIP PG-41: This accessory boosts the battery capacity of the camera by holding up to two dedicated batteries. In combination with the battery inside the camera, this accessory makes it possible to enjoy up to 300% more shooting time. ELECTRONIC FLASH EF-630 (SA-STTL): The high-power EF-630 flash enables S-TTL automatic flash metering. It has wireless flash connectivity and a high-speed synchronization function that can be used at high shutter speeds, giving photographers further scope for creative expression.
