Sigma SD Quattro H

For the Image Quality Purist.
The sd Quattro is a highly unique APS-H sensor mirrorless camera designed with the Foveon Quattro sensor. This sensor is renowned for its incredible image quality and color fidelity and produces imagery comparable to that of a 51MP DSLR with a Bayer-pattern sensor. Its new physical design touts a two mode autofocus system, utilizing phase detection and contrast detection for optimal performance while a dust & splash proof magnesium alloy body make this system rugged and ideal for harsh conditions. While in “Auto”, a new 2.3MP viewfinder will toggle between the eye piece when the photographer raises the camera to their face and then toggle to the LCD screen as the photographer lowers the camera. The Super Fine detail mode takes full advantage of the Foveon sensor, capturing 7 different exposure in one click for the ultimate dynamic range (image can be extracted individually). The Sigma sd Quattro is manufactured to use the Sigma Global Vision lenses, renowned for their super IQ and performance.

  44.8MP APS-H Foveon X3 Quattro CMOS Sensor & Dual TRUE III Processing Engine.
At the heart of Sigma's digital imaging system there has always been a Foveon sensor. This 44.8MP APS-H format Foveon X3 Quattro CMOS sensor represents the latest in this technology, offering outstanding resolution and rich color with smooth gradations and a wide dynamic range by using a layered pixel array. This system stacks the red, green, and blue pixels vertically with a 1:1:4 pixel ratio, allowing full color information to be collected at every photosite and a resolution equivalent to that of a 51MP Bayer array. Additionally, the top layer of blue pixels has a 25.5MP array, resulting in natural raw image data of 6192 x 4128 pixels.

Sigma SA Lens System.
Featuring Sigma's SA interchangeable lens mount, nearly every single one of their respected Global Vision series of lenses will be available for use with the sd Quattro H. This model features an APS-H size sensor which has a crop factor of approximately 1.3x, meaning that a 50mm lens will have the equivalent field of view of a 65mm lens on a full-frame sensor. Additionally, the lens mount has complete electronic communication, ensuring all functions and features, including autofocus, optical stabilization, and more work correctly.

Dual LCD Monitors & Electronic Viewfinder.
For composing images and reviewing settings, a bright 3.0" 1.62m-dot LCD is available on the back of the camera. Unique to the sd Quattro series is a sub monitor adjacent to the main LCD which provides constant access to your most critical settings, including aperture, shutter speed, and more. These screens are covered by the same sheet of protective glass for a seamless appearance. For users looking for a more natural eye-level shooting stance, the sd Quattro H is also equipped with a 2.36m-dot electronic viewfinder with a 1.09x magnification. A dedicated switch is available for quickly changing between the monitor, viewfinder, or an automatic switching setting.

Hybrid AF System.
Equipped with both phase-detect and contrast-detect points, the sd Quattro H can capture moving subjects with ease and lock on in no time at all. The system has up to 9 selectable points as well as free move and face detection. Additionally, it has been optimized to function in a range of shooting conditions with an operating range of -1 to 18 EV.

Super-Fine Detail Exposure Mode.
Maximizing the performance of the stellar Foveon sensor technology is the Super-Fine Detail exposure mode. This creates seven different exposures of the scene which are then blended into one raw file in X3I format. Combined with processing form the Sigma Photo Pro software, a photographer can work with image data that is super clean and with a wide dynamic range. This can greatly benefit studio and tripod-based work.

Body Design.
Known for distinctive camera designs, Sigma's sd Quattro series sports a very unique design with a comfortable grip and physical controls designed for intuitive control. This includes a Quick Set button near the shutter that instantly brings up the Quick Set Menu for access to your most commonly used settings while continuing to look through the viewfinder. On the top of the body, in addition to two command dials, is a Lock switch that prevents accidental changing of settings. This can be further customized to lock only select buttons for ideal functionality. On the rear of the camera are several additional buttons all easily reachable by the right thumb, including the menu button, focus frame button, and AEL/AF button with lever.
