Excerpt: This is not a camera for everybody and wouldn't be a good choice for a single camera. It works well only in good light at low ISOs.However, it works so incredibly well in low light, producing absolutely beautiful image quality, that it seems worthwhile as long as you accept its limitations. The results show great resolution. Whether that great resolution is 29 megapixels or 39 megapixels, is subject to much debate.
Pros: Excellent lens, Great Resolution, Great Value, Phenomenal Image Quality, Unique Design
Cons: No Viewfinder, Poor in Low Light, Short Battery Life, Slow Raw Converter
Excerpt: I made images from this and my EM5 with a 12-35mm 2.8l Panasonic lens to get as close a comparison as possible. In flat light the difference is hard to tell, there certainly is a little more resolution but my non photographic friends didn't pick up on it. When there is some tonal range like clouds at sunset the difference is impressive. The raw converter while slow puts Camera Raw and DXO with my Olympus to shame. Absolutely increditable.
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...
