Summary: I think there are too many digital SLR camera's in the market. For example Canon, Nikon, Sony, Pentax and others. All of them are really good and atractive for costumers. As I want to buy Full Frame digital camera, unfortunatelly I haven't still one. many days I have spent lots of hour in the internet and looking for handful cameras. And one day I see Sigma SD15 for a reasonable price and no doubt to take it. Me as I am this camera is the best for me.
Summary: I bought the SD 15 as an upgrade to the SD 14. As an upgrade it is a good upgrade, kind of a Sd14 mark II. The controls are similar so there is not any great learning curve. The addition of the QS menu from the DP series is a great addition and makes the camera easier to use. The SD 15 now has more advanced flash settings that the SD 14 lacked. The image quality is excellent and detailed using RAW. The SD 14 had a good JPEG engine, the SD15 does not.
Excerpt: Browsing the net I stumbled across a small quantity of new Sigma SD15's on sale for a good deal less than £350! So my frustrating SD14 was put up for sale and provided me with almost the purchase price of a new SD15. My hopes that the SD15 would be a better camera seem to be confirmed. I'd become hooked to the SD range ever since using an SD9, and finding that the image quality is unsurpassed by any other digital camera I had used.
The SD15 will teach you a few things about photography.

Summary: I have gained the most from this camera in the form of education. I am a beginner in digital photography. I didn't know much about shutter speed, etc... I had to learn these things to get images from this camera. I am satisfied with the results I get and the more I learn about photography the better my images get. I really enjoy using the EF 610 DG Super Flash also. It is a must have if you ask me.
Excerpt: After the great experience with the SD14 I can say that the SD15 is even better. Electronic improved, much faster processor, better noise treatment, very smooth in all the aspects. Dynamic range excellent, colors very naturals and reals. Pics looks great . The leaves , flowers , trees at landscapes looks naturals and clears. True colors sharpness and very high definition. Its a marvel. Next step is the SD1 46 mgplxs. but much too expensive yet.
Summary: I received my copy of the SD-15 in July 2010 after waiting for it for 2 months. It came with over 1000 shots already in the shot counter, but with a new camera warranty from Sigma USA. Don't settle for anything less than a totally "legitimate" purchase from a real dealer. I didn't: the Sigma USA warranty was the important thing. When I got it, I also got a Sigma 50-200 F4-5.6 OS lens for what I thought was a too-cheap price of $169.
Summary: I have owned several Sigma cameras and have a love/hate relationship with the breed. To generalize, I find them like an old person---rich in capability but somewhat slow and cantankerous to live with. I rail at my Sigmas but miss them when I leave them home. In any case, I purchased this SD15 to replace my SD14 which had white balance issues that I was tired of dealing with. This slightly refreshed version is vastly better at analyzing light and properly rendering it.
Summary: The people who say this is not a real 14 megapixel camera don't understand how Foveon sensors work. A picture is not just a bunch of dots (pixels), it is a combination of colors and their intensity. While a Canon camera might make JPG files that technically have more megapixels than a Sigma, the amount of color information in the Sigma picture is still better. Also if you think 2640x1760 resolution is somehow not good enough for full size prints then you're on crack.
Product of the future . . . but not of the present!

Summary: The sigma camera line is built around a sensor, the Foveon, that is technically different from any other. Since it comes closest to film in registering color, it produces images with drop-dead gorgeous color range and detail. Color is more true to life, and required virtually no post editing. The problem is that the image size itself. When it comes to enlargements later you'll discover that your pictures are less than 5 megapixels each-- very small files.
