1. According to the focal length, the DP series is divided into DP1 (equivalent to 28) and DP2 (equivalent to 41). The product developed a serious color cast in 2007, has been discontinued, and its users have basically disappeared.
2． , DPS series is divided into DP1S and DP2S according to focal length. The 2009 product has also been discontinued, and some users are playing with it.
3. According to the focal length, the DPX series is divided into DP1X (equivalent to 28) and DP2X (equivalent to 41). This product was discontinued in 2010. Image quality is already very good. People are playing, the DPX uses Kodak's 14-megapixel X3 Sigma patented X3 sensor, which is a unique 2.5-inch 230,000-pixel LCD screen.
4. DPM series, currently the main product of the DP series (produced in 2013), is divided into DP1M (equivalent to 28), DP2M (equivalent to 45) and DP3M (equivalent to 75 focal length) according to focal length. . Aperture, for example, the focal length of DP1M (fixed 19mm f/2.8 lens) is 19, and the maximum aperture is 2.8.
Because DP uses a C-frame sensor, the actual focal length is multiplied by the conversion factor 1.5, so the actual angle is the view DP1M or the equivalent focal length is 28, DP2M, 3M, etc. The DP1-3M features Kodak Technologies' patented 15-megapixel X3 sensor, which features a 46-megapixel C-frame sensor and a 920-megapixel LCD screen for stunning image quality.
5． , the DPQ series released by Sigma has improved sensors, chips and lenses. Expensive and unstable user reputation. The obvious advantages are extended battery life and direct JPG output, but some users report inferior quality to DPM.
6. In addition, Sigma also produces SD1MSLR. In 2012, the chip and sensor were the same as the DPM, and the lens could be swapped. A 460,000-pixel LCD screen is used, and the image quality is basically the same as DPM.
7. DP series cameras are cameras with obvious advantages and disadvantages.
