Excerpt: Great camera very high Quality built. It has great Dynamic Range due to its unique image Sensor processor design my only problem is that you can't use this camera as main camera in indoor/low light photography due to its LOW ISO range and even in above 1000 you see grain other than that its a great...
Pros: Good Battery Life, Great Resolution, Great Zoom, Large Clear LCD
Summary: The Sigma SD1 can give out-of-this-world results in terms of resolution & Clarity...but you have to accept some shortcomings. The operation and write times are from a bygone era...and users of modern super fast cameras will be frustrated.
Summary: The ultimate Foveon-based digital SLR, loaded with features and of an excellent build quality. I gave it only 4 stars as it doesn't have "live view" of the image you plan to capture using its LCD screen, only the viewfinder. Its an unexpected omission and one I hope they correct in any future model.
A truly unique, exciting, alternative to the "Canikon" fleet

Summary: Most people are not aware that when they buy a conventional (e.g. Canon or Nikon) digital camera, the sensor is what is called a 'Bayer array' and has a fundamental shortcoming: each sensor only recognizes one of the three primary colors (red, green, or blue).
Excerpt: This is a first impressions report; got my SD1 for 2 weeks now, with firmware 1.03. I own Sigma SD14 and SD15 cameras, so this SD1 is my third Sigma camera. I use Sigma cameras since 2008 and can say than the SD1 is the best one I have used so far.
Pros: 2 Dials For A-s Settings, Easy To Use, Good Image Quality
Excerpt: So, I have this camera, and a Nikon D800. The short review is that I love this camera for color rendition on still subjects, such as flowers or scenics... even if getting there requires jumping through the hoops of a slightly quirky camera, and Sigma's software.
Pros: Good Image Quality, Quiet, Simple Feature Set
Excerpt: I really want to love this camera for its superb sharpness and 3d image quality. Its definitely got the Sigma look to it. Much improved over the SD15 except in one area; Color. The colors don't pop like they did on the older models, including the DP series. Maybe its all those pixels.
Pros: Good Image Quality
Cons: Noisy At High ISO, Poor In Low Light, Short Battery Life
Excerpt: It is the best classic DSRL camera on the market. The most important is an excellent image quality this camera provide. It has user-friendly and classic interface and bright screen. Moreover, it provides the possibility of infrared photography.
Pros: Easy To Use, Fast Shutter Speed, Good Image Quality
Excerpt: I own both the Sigma SD14 & Sigma SD15 and have been very happy with the way they handle color.I do fine art landscape and nature photography so I looked forward to having the higher resolution of the Sigma SD1 Merrill. I just tested the camera on a trip to Costa Rica.
Pros: Very sharp images
Cons: Must correct warm bias, Noisy At High ISO, Poor In Low Light
