Used Sigma dp0 Quattro Digital Camera with 14mm f/4.0 Lens

The Sigma dp0 Quattro incorporates a fixed, high performance 14mm F4 lens, which is equivalent to a 21mm lens on a 35mm DSLR and is optimized to maximize the performance of the series' Foveon "Quattro" Direct Image sensor. The Quattro line is great for photographers seeking a unique product, and the 14mm F4 lens is meant to take full advantage of the Foveon sensor.

In order to achieve the highest optical performance, the dp0 lens features four "F" Low Dispersion (FLD) glass elements, which have performance equal to fluorite, two Special Low Dispersion (SLD) glass elements, and two aspheric lenses, including a wide double-sided aspheric lens. This reduces chromatic aberration and distortion, which are characteristics typically present in super wide angle photography. The camera offers sharp rendering performance from the maximum aperture, and the superior telecentric optical design improves image quality throughout the frame and maximizes the sensor's ability by passing on information about subjects to the sensor. In addition, the wide angle of view of 91 degrees and depth of field are ideal for architectural structures, interior photography and landscapes. With this powerful lens and sensor, numerous glass elements to reduce distortion, and a 91 degree angle of view, this lens is ideal for landscape and architecture photography.

As with all the cameras in the Quattro series, the dp0 Quattro features the distinctive styling of the line. The Quattro sensor is the equivalent of a 39 MP conventional Bayer sensor in resolution testing. The next generation sensor builds on the distinctive properties of the x3 technology, which uniquely records red, green and blue wavelengths at each pixel location within three layers.

The Quattro sensor is a three-layered, panchromatic silicon chip whose green-sensitive middle and red-sensitive bottom layers each have 4.9 MP and record only color/chrominance information. The top blue layer captures chrominance and resolution/luminance information with 19.6 MP, resulting in greater detail capture and resolution capabilities that are higher than the Merrill DP camera line. The Quattro sensor's architecture also contributes to true color rendition, more detail capture, and faster image processing, all of which delivers even more realistic images.

The dp0 Quattro camera also features
• Optional dedicated Optical Viewfinder VF-51 that offers accurate framing and makes composition easier as it is unaffected by external light conditions
• The TRUE III Image processor, providing ultrafast processing of an immense volume of image data without any deterioration of the final image • Better high ISO performance with one to two stops of improvement
• Improved 3A performance: Auto Color Mode, Auto Focus and Auto White Balance
