Sigma SD10

<h2 id="foveon-x3-image-sensor">Foveon X3 image sensor</h2>
<p>Like its predecessor, the SD10 uses a sensor with the unique <a href="/facts/Foveon_X3/6yWB5NrF">Foveon X3</a> sensor technology. The 10.2-million-pixel <a href="/facts/Raw_image_format/1T6qygdz">raw file</a> generated from this sensor is processed to produce a 3.4 megapixel size image file.  Although the image file is smaller than images from competing 10 megapixel cameras, it is made from the same number of measured data values because the Foveon sensor detects full-colour data (three values) at each photosite; the actual resolution contained in its 3.4 MP images is about the same as a conventional <a href="/facts/Bayer_filter/yC8UPoVU">Bayer filter</a> sensor of 7–9 MP.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>  Sigma and Foveon count each red, green, and blue sensor as a pixel, and state the camera has 10.2 million pixels; similarly, companies selling Bayer filter cameras also count each single-colour sensor element as a pixel.

<h2 id="raw-output-only">Raw output only</h2>
<p>Unlike other DSLR cameras marketed concurrently, the SD10 performs no in-camera processing to common image formats such as <a href="/facts/JPEG/HQ8QS3uB">JPEG</a> and <a href="/facts/TIFF/TjBJcLeT">TIFF</a>.  Instead, it saves images in its own .X3F format, which retains all the information the camera captured.  Processing on a computer is required to use these files.  Sigma provides the Foveon-written SIGMA Photo Pro application for this purpose; in addition, <a href="/facts/Adobe_Photoshop_CS2/f6bbmNx0">Adobe Photoshop CS2</a> supports the format, as do several other image-processing applications.
</p>
<h2 id="shooting-modes">Shooting modes</h2>
<p>The camera supports single-shot, continuous, 2 or 10 second self-timer, mirror lock-up, and auto <a href="/facts/Exposure_bracketing/p3ueF7sr">exposure bracketing</a>.
</p>
<h2 id="exposure-modes">Exposure modes</h2>
<p>Four different exposure modes are supported: aperture priority (A), shutter speed priority (S), manual (M) and program automatic (P).
</p>
<h2 id="lens-availability">Lens availability</h2>
<p>The SD10 supports only <a href="/facts/Sigma_SA_mount/7s1PySXl">Sigma SA mount</a> lenses. Only Sigma produces lenses to fit this mount.  Third-party converters exist for a number of other lens mounts, although no automatic features are supported. Many Canon <a href="/facts/EF_lens_mount/YMWYE90s">EF mount</a> lenses can be converted to SA mount while retaining autofocus and camera controlled aperture settings, however optical stabilisation will not work.
