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-dots electronic viewfinder features near-100% viewfinder coverage and a 1.10 magnification ratio (sd Quatto H: 0.96x). 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.
In addition to the 1.62 mega-dots 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.
In addition to SIGMA’s original RAW format (X3F), DNG (Digital Negative) format is available.
DNG is the RAW image data that is developed by Adobe Systems Incorporated. DNG file makes it possible to develop images on other softwares, which gives more choices of expression.
DC Crop Mode
The Sigma sd Quattro H incorporates an APS-H sized image sensor, and it automatically switches to DC Crop Mode, when DC lenses are attached. Also, it is possible to select On/Off of the DC Crop Mode manually. When a DG lens is mounted and the DC Crop Mode [On] is selected, the coverage of the LCD monitor and the view finder automatically becomes within APS-C size, which makes it easy determining the composition.* If [On] is selected, the angle of view will be equivalent to 1.5 times longer than the focal length of the lens and the number of pixels to be recorded will be smaller.
