Summary: After using the Sigma DP2 Merrill (and the DP1 and DP3 Merrill) for almost 2 years, the DP2 Quattro is a welcome upgrade in usability and image quality. Here's what I like about the DP2 Quattro compared to the DP2 Merrill: 1. Improved battery life, 2-3 times as many shots on one charge. I rarely need to change the battery more than once a day. 2. Much faster write times. Under 5 seconds shooting RAW+JPEG. 3. Higher resolution display (no more jello shake). 4.
$1000 for a million dollar image- The bar has been raised

Summary: In the not too distant future, the images from cameras will simply match that of the human eye. We are getting closer and the Foveon sensor is knocking on the door of that goal. I too just sent back the test camera and couldn't have reviewed it better than DD did. He/she nailed it. Shoot a daylight low or medium contrast scene at 100 ISO and this camera will blow you away with the subtle depth in color and overall sharpness.
Summary: definitely a photographer's camera. no frills. slow. take your time to compose. best image. excellent solid body. beautiful lens. so you cannot use for instant shooting. have to plan ahead and stabilise the body. fine with me, i am slow.
Summary: Pros * with sufficient light, it takes outstanding photographs * the detail is incredible * light weight Cons * lousy battery life Note 1: It's not a consumer-friendly point-and-shoot, nor an action photographer's dream. I'd done my research and knew what the Merrill's strengths and weaknesses were before purchasing. I'm not going to ding it because of its limited useful ISO range, slow write speeds, or slow auto-focus.
Excerpt: As others have said, this camera belongs on a tripod with 2 second shutter delay. The images are better than my $3000 canon with $2000 L lens attached. Used within its limits, this camera produces the best image quality I have seen out of any camera. The B&W conversions made from the raw files from this camera are very good, also better than any other digital camera I have used.
Summary: Extra batteries are needed. Tripod is necessary for low light. Processing picture is slow. Focusing in low light is slow. BUT, the picture quality is insane! That's all you need, isn't it? Buttons and UI are straightforward. The focus ring is smooth. SPP software is simple and works well.
Summary: If you get this, you can not be a beginner or you will find yourself out of depth. It is clunky and not the best interface out there. That said, it is at this point in time at least not as horrible to use as some of the reviews I read. It will not compare well on usability with the newer similar cameras like OM-D or X series Fuji, but as far as resolution is concerned, I have not been able to touch it with anything short of D800E with a rather expensive lens, and even...
No 36MP bayer sensor can out resolve Sigma's 15mp Foveon Sensor.

Summary: there, i said it. The foveon sensor is 46MP, because each pixel has a r,g,and b signal. In monochrome, I think the image quality is matched by the 5D mark II or III, because without the color information the blue and the red signals blend with green, and all together. It still beats an 18mp B&W image, but maybe not a 36MP one. Be that as it may, in color you can easily produce 9000X7000 pixel images that print up like medium format film, or medium format digital.
Excerpt: Not only does this produce the best IQ I've seen from any compact camera, it rivals a lot of DSLRS and medium format cameras that are several times the price. It's not the fastest tool, but it suits my style perfectly. I primarily shoot architecture and more carefully set-up street work.
Pros: Easy to Use, GREAT IQ, Great Resolution, Large Clear LCD, Nice User Interface, Small / Compact
