Sigma DP1 Quattro
Latest in the Sigma’s lineup of high-resolution fixed-lens compact cameras comes the Sigma DP1 Quattro, at photokina 2014. The DP1 is the wide angle variant of the DP2 Quattro which was announced earlier.
The DP1 pairs a 19mm f/2.8 lens (28mm equivalent focal length) with Sigma’s proprietary X3 Foveon sensor technology for stunning image quality.
The sensor in the Quattro sees a change in pixel structure from the original format of the Foveon sensors. Instead of recording red, green or blue on adjacent pixels like most traditional sensors, these sensors originally layered three photosites on each pixel. Thus each pixel can record red, green and blue colours, effectively images that are 14.3 x 3 million pixels.
With the Quattro, the pixel stucture has changed. With the top layer the camera captures 19.6MP but the lower layers capture only 4.9MP. The final output image is therefore restricted to 39MP as opposed to the 46MP files created by the Merrill series cameras. According to the company this has helped improve the already stunning image quality and dynamic range. It also improves up on the ridiculously bad high ISO performance of the Merrill cameras (Images beyond ISO 400 were not useable!).
Sigma has also announced the LVF-01 magnifying loupe which allows the rear LCD to be used as an electronic viewfinder.Tags: APS-C, Sigma DP1 Merrill, Sigma DP2 Quattro, sigma dp2 merrill, Sigma DP3 MErrill, photokina 2014, Sigma DP1 Quattro, foveon sensor X3, high resolution compact cameras, fixed focal length cameras, LVF-01
