Excerpt: This camera is not for everyone but, if you can put up with a few quirks (fixed lens, slow operation, poor battery life, lack of compatability with all but Sigma's proprietary post processing software, poor low light operation, etc.) the results, at least to date and for what it is good for, are stunning.
Pros: Good Image Quality
Cons: Lag / Shutter Delay, Short Battery Life, Sigma Viewfinder Bad
Summary: Let me start by saying that despite the astronomical price and the unnecessary misleading advertising. the Sigma Merrill DP1 is in fact an excellent camera for shooting in bright light but since Sigma is insisting in deceiving people with their childish 46 Megapixels claims I have no choice but to explain to the newcomers that they will NOT get 46 Megapixels out of this camera but actually one third of that.
Excerpt: I wanted to take multiple exposures to capture HDR with this camera but the slow write speed to the memory card caused me to miss getting other pictures I wanted. I thought it might be the speed of my memory card but I tried faster ones and it didn't seem to help. It takes up to a minute to store the pictures for HDR.
Summary: Great cam, but you really need to know what you're doing. Keep in mind: - it's slow as hell - processing RAW pics takes forever, software isn't very good - you only should take RAW pics, JPEGs straight out of the camera are very bad - uncomfortable menus, clumsy operation Apart from that, if you really want to try the Foveon sensor and see the IQ difference it makes for yourself (like I did), this is a great option (if bought cheap)
Summary: I--like many others--had high hopes for this camera. A (nearly) DSLR sized sensor in a compact body is a very attractive concept, and it is one that I hope and assume will be developed and improved upon by Sigma and other makers. Having such a large sensor means that noise--the primary problem with compact digital cameras--is vastly reduced and effectively neutralized as a negative issue.
Summary: I just read all reviews here at amazon and I'm glad more buyers were happy about their DP1. I actually pre-ordered my DP1 from amazon a few months ago before it was released. I was not so happy with it at first until after 2 weeks of using it. (I don't know if I'm actually happy or I just got used to it after 2 weeks.) I understand that it is made for Making pictures and not Taking pictures.
Summary: dp1 is a great camera, but it really is not a point and shot. specially for portrait, it's a bit too slow to capture anything with only small movements. for still life, it's a great camera if you learn how to use it. the noise level is really really good compared to any other point and shot. but compared to DSLR the resolution desires a bit more.
Summary: The DP1 is the first of its kind. A compact camera with a large sensor similar to a mainstream DSLR rather than the usual tiny sensor found in all other compacts.. Sigma's number one goal was image quality and they sacrificed a lot of other things to get it, so this is not a camera for everyone. On the plus side this is a very well built, metal bodied camera with a high quality lens, DSLR sized sensor and phenomenal image quality in well lit conditions.
Summary: On paper, this was the camera I had been looking for to complement my Canon EOS. The image quality is very good, yes: - The sensor is dSLR-sized, so IQ is good even at high ISO. - The lens is fixed, and very sharp. - You can shoot RAW for detail or flexibiliy. Regarding megapixels: this camera does NOT have 14MP, but a third of that. There's tons of info on the web about the peculiarities of the Foveon sensor, which, yes, has more "resolution per pixel".
