Sigma SD Quattro H Foveon Compact System Camera

In return to the newly introduced SD Quattro, Sigma also welcomes the release of the SD Quattro H. A mirrorless camera that carries 26.6×17.9mm (1.0 inch×0.7 inch) APS-H sensor with 44.8 Megapixel Foveon X3 Direct Image Sensor(CMOS). It is also capable of capturing precise image information carried by visible light. Dual TRUE III Engine utilizes the image processing of Foveon X3 sensor delivering an extremely detailed image expression with a noticeable 3D touch. SD Quattro is created with Magnesium alloy body, 23.5×15.5mm (0.9 inch×0.6inch) APS-C sensor to accommodate a wide range of user needs and built-in Electronic viewfinder with almost 100% coverage and 1.09 magnification ratio. The camera’s 3.0" TFT color LCD monitor clearly displays all the critical information including the remaining shots, aperture value, shutter speed, ISO level, and more. The ISO however ranges from ISO 100-6400. SD Quattro yields to USB3.0, micro B interface. 

Product Features in Detail

An image processing system ready for higher resolution. Outstanding performance, next-level image quality.
With its three-layer structure, the Foveon X3 Quattro direct image sensor captures all of the information carried by visible light. This film-like capture system offers rich gradations and color and truly distinctive image quality. Optimized to match the enhanced resolution and other characteristics of the image data, the image processing system of the new SIGMA sd Quattro leverages the outstanding fundamental functions of the camera while taking overall image quality to the next level.

Two sensor sizes available
The SIGMA sd Quattro incorporates an APS-C size sensor for outstanding medium format level image quality, while the SIGMA sd Quattro H features a new APS-H size sensor for 51 megapixel-equivalent ultra-high image quality.

Foveon direct image sensor
The world’s only image capture system to use vertical color separation technology

Newly developed Foveon X3 Quattro direct image sensor
Now featuring 39 megapixel-equivalent ultrahigh resolution

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
Speed versus focusing performance: two AF detection methods available for smoother and more accurate autofocusing.

New Super-Fine Detail exposure mode
New SFD mode for lower-noise, higher-definition images

Continuous shooting of up to 14 images in RAW format
The DDR III high-speed, high-volume memory is approximately twice the capacity of that of the SIGMA dp Quattro. This allows the SIGMA sd Quattro to capture up to 14 RAW images (X3F files) in High size during continuous shooting (SIGMA sd Quattro H: up to 10 images). Leveraging high-speed data transfer and processing, the SIGMA sd Quattro offers a continuous shooting speed of up to 3.6 frames per second (SIGMA sd Quattro H: up to 3.8 frames per second). As a further option, when Low size is used, the SIGMA sd Quattro offers a continuous shooting speed of up to 5.1 frames per second and continuous shooting of up to 28 images (SIGMA sd Quattro H: up to 20 images).

Aiming for the ideal interchangeable lens digital camera
An sd Quattro series camera provides a feeling of solidity and superior usability when you take it in both hands to compose and shoot. Each is developed to have just the right weight and shape for portability and to offer better expandability as a complete system. Moreover, each features an ergonomic design to support an intuitive photographic experience.

High-resolution Super-High size images
JPEG files in S-HI size (SIGMA sd Quattro: 39 megapixels; SIGMA sd Quattro H: 51 megapixels)
A variety of file sizes is available to accommodate a wide range of user needs. Using High-size files brings out the best performance from the image sensor, while using Low-size files increases the number of shots that can be stored in memory. In both of these file sizes, the camera can simultaneously create RAW and JPEG data. In addition, the camera can create JPEG files in S-HI size (SIGMA sd Quattro: 39 megapixels; SIGMA sd Quattro H: 51 megapixels), appropriate for large prints, as well as in S-Lo size, which is ideal for online sharing.

High-resolution electronic viewfinder
The high-resolution 2.36 mega-pixel electronic viewfinder features near-100% viewfinder coverage and a 1.09 magnification ratio. The viewfinder incorporates three lenses with the outermost lens specially coated to ensure a clear field of view. Using a switch next to the viewfinder, the user can toggle between displaying the image in the viewfinder and the monitor. In AUTO mode, the camera automatically switches to the viewfinder display when the user is looking through it and to the monitor when he or she is not. This mode allows seamless use of the viewfinder to take photographs and use of the monitor to access settings and confirm results. For extra convenience, many functions of the monitor are available via the electronic viewfinder itself, such as setting values, grid lines, electronic level, zoom, focus peaking and more.

Focus peaking function
This function puts a colored outline (white, black, red, or yellow) around the subject in the viewfinder for instant confirmation of the person or object currently in focus.

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.

Intuitive user interface helps user focus attention on creative work
Building on the success of previous SIGMA user interfaces, the new UI is more intuitive than ever. Located next to the shutter button, the Quick Set button provides instant access to the Quick Set Menu, which allows the user to quickly adjust commonly used settings while continuing to look through the viewfinder. Located on the top of the body, the LOCK switch prevents the accidental pressing of buttons, helping keep the user’s attention on the creative work. The buttons that are locked with this switch may also be customized by the user. Located on the rear of the camera near the selector are several controls for commonly used functions. Easily accessed with the thumb of the right hand, they include the menu button, focus frame button, and AEL/AF button with lever.
