FISHING BOATS UNDERGOING MAINTENANCE AT HOWTH BOAT YARD - 9 JANUARY 2009
I used an original Sigma DP2 which was close to impossible to use.
The Sigma DP2 was described as a high-end compact digital camera by the Sigma Corporation. It featured a 14-megapixel Foveon X3 sensor (2652 × 1768 × 3 layers), the same sensor used in its predecessor, the Sigma DP1 [which I also had but it no longer works] and in the Sigma SD14 DSLR, a fixed 24.2mm f/2.8 lens (41mm equivalent), a 2.5” LCD and a pop-up flash.
With its predecessor, the DP1, was one of the few "compact" cameras that featured a sensor with a size equivalent to APS-C. Sigma claimed this (comparatively large) sensor size would result in DSLR quality images from a small, pocketable camera. The camera did not include auto or scene modes as it is not aimed at the average consumer. The DP series cameras were therefore targeted at professional photographers or enthusiasts seeking a compact, yet capable camera.
The DP2 was announced in September 2008, and began shipping in 2009. Mine must have arrived early in 2009 or late 2008.
Differences to the DP1 included a lens that is one stop faster, f/2.8 vs. f/4.0, 24.2 vs. 16.6mm(35mm equivalent of 41mm vs 28mm) and a faster processing chip, the True II image processor, which is shared with the Sigma SD15 DSLR.
Though claimed difficult to use, it shares many features and limitations found in rangefinder cameras such as the Leica M6, and with its mechanical-feedback manual focus, snaps images with zero shutter lag.
In February 2010, Sigma released an updated version of the camera, the Sigma DP2s. The DP2s offered a new AF algorithm, a "power save" mode and a modified rear design with new labelling of the buttons. The imaging sensor itself remained the same.
In 2012, Sigma released the 'Merrill' range of the DP series, with a much improved sensor.
I currently still use a DP Merrill and a DP Quattro but while I like the results [when they perform as expected] I would not really recommend any of them especially as results are unpredictable and because battery life is dismal.
It should be noted that the Merrill Series of cameras produce RAW images that cannot be processed by software such as Adobe Lightroom.
Personally I like the Merrill but they battery life varies from 40 to 50 images.
