The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan. It is fitted with a Sigma SA mount which takes Sigma SA lenses.
The camera was announced on August 29, 2006 with a "teaser" advertising campaign and was unveiled at the photokina trade show in Cologne, Germany on 2006-09-26. After production delays, Sigma announced the official release of the SD14 to be on March 6, 2007. Sigma has released sample images on their website. Contrary to most consumer cameras, which use color sensors based on a Bayer color array, the SD14 uses a Foveon X3 sensor. Also peculiar is the fact that the infrared filter is on the lens mount and doubles as a dust protector, sealing the mirror and sensor compartment, and can be removed easily, to allow infrared photography.
The camera uses the SA mount, for which only Sigma itself manufactures lenses.
Physically, the SA mount is identical to the PK mount with a reduced back-focus of 44.0mm (equals Canon EOS) as opposed to the 45.5mm of Pentax PK and M42. The Sigma SA lens protocol is a clone of the Canon EF protocol. This provides a not so obvious but very interesting option that most Canon EF-mount lenses will work seamlessly after exchanging the mount plate with the Sigma DSLRs, but without image stabilization.
Pentax K-mount lenses physically fit, but should only be mounted when the rear protrusions have been dismantled. Such lenses will then focus beyond infinity and may contact the protective filter. A spacer ring (made e.g. of decopperized FR3 1.5mm circuit board) can be added between the K-mount lens body and its bayonet plate. Prime (as opposed to zoom) lenses often permit a simple resetting of the position of the focusing ring on helical inside. Zoom lenses converted this way will become vari-focals by losing the focus setting as they are zoomed. The spring that opens or closes the lens iris in the K-mount lenses may have to be reset to work in the opposite direction.
