SIGMA SD9 DSLR CAMERA

VISITOR'S GUIDE TO CORK BY WILLIAM MURPHY

MY EQUIPMENT AND RELATED TOPICS


This was my first Digital SLR camera and while it could under the right conditions produce some wonderful it was in general unusable. Six months after I purchase the SD9 I gave up and purchased a Canon 5D.

SORRY FOR THE DELAY
The Sigma SD9 is a digital SLR camera produced by the Sigma Corporation of Japan.

The camera was launched at the Photo Marketing Association Annual Show on February 18, 2002. It was Sigma's first digital camera, and was the first production camera to use the unique Foveon X3 image sensor, which reads full colour at each pixel site. Other sensors detect only one colour at each site and interpolate to produce a full-colour image.

The SD9 had two separate power systems; one set of CR-123A lithium batteries in the handgrip powered the camera functions, while another pair of CR-V3 batteries or four AA size rechargeable in a battery tray in the base powered the digital functions. This split power system showed that the camera functions (inherited from Sigma's SA-9 film SLR) were not integrated at all with the digital half.

Another unusual feature of the SD9 was its "dust cover" filter right behind the lens mount, to prevent dust getting into the chamber and onto the sensor when changing lenses.


Reviewers and users reported good results in good lighting, but poorer ones in low light using either high ISO sensitivity or longer exposures.

The SD9 was succeeded by an updated model, the SD10, which addressed the power and low-light issues.
