Conclusion: The Sigma SD15 has three features, which are unique and which some may consider makes it better than most other (non-Sigma) DSLRs. On the other hand, it lacks a number of features found in most other current DSLRs: So do the former make up for the latter? Unfortunately, for 95% of potential users, I don’t think so. While the Foveon sensor is said by some to give better color rendition, sometimes described as a “almost 3-D effect”, I really don’t see it.
Conclusion: And that's a shame. It's great to see such an innovative approach to digital imaging, and the quality of the Foveon X3 sensor's images is remarkable. We can only imagine what could be achieved if it could be developed into larger, higher-resolution versions.
[Review] Sigma SD15, a very puzzling DSLR, the Light Review edition.
18 April 2010
Excerpt: We have been testing quite a lot of camera, but never we have been so puzzled by a DLSR before. Sigma has been in the Photography business for quite some times now and made not only impressive lenses, but also really amazing Point &
Summary: The Sigma SD15 is an oddly eccentric fourth attempt at a high-end digital SLR by a manufacturer still better known for its accessories. Good results are achievable, but, by golly, you have to work for them.
Cons: Very noisy results at higher ISOs; no live view capability; no video capture.
Summary: A well-built DSLR camera for photographers who want to work with raw files to obtain maximum image quality.It's taken a while for Sigma's SD15 to reach the market. First displayed at Photokina 2008 and then officially announced as a successor to the SD14 on 20 February, 2010, the SD15 has only just gone on sale locally. It offers a few updates to its predecessor but features the same Foveon X3 sensor, which has a focal length crop factor of 1.7x. . .
Pros: You want a DSLR camera that will deliver sharp, colour-rich images and are prepared to work with raw files., You want a camera with P, A, S and M shooting modes, and no fancy additions., You want a DSLR with a built-in auto flash plus useful flash modes and exposure adjustments. Don't buy this camera if :, You want to shoot video., You require easy-to-use automated shooting modes., You want simultaneous RAW+JPEG capture.
Excerpt: With its bulky body trumpeting a semi-professional status, Sigma’s new digital SLR - the Sigma SD15 - offers 14.06 effective megapixels. But, because its unique sensor is triple layered, with one silicon-embedded layer of photodetectors each for absorbing red, green and blue, the pixel count for any JPEG shot is actually around 4.6 megapixels.
Pros: Compatible with over 40 lenses; unique Foveon X3 CMOS sensor; chunky build and rugged feel.
