Overview — Sigma SD14

The Sigma SD14 is a DSLR camera built around a uniquely structured sensor that sets it apart from conventional single-layer imaging systems. Its APS-C sensor delivers 4.7 MP effective resolution across 2652 x 1768 pixels, but the architecture goes deeper — 14.1 million photodiodes arranged across three layers are processed by Sigma's TRUE (Three-layer Responsive Ultimate Engine) image processor. On the output side, the camera produces interpolated JPEGs at up to 4608 x 3072 pixels, while RAW files reflect the native 2652 x 1768 capture.

The SD14 uses the Sigma SA lens mount, keeping it within Sigma's own optical ecosystem. Autofocus is handled by a 5-point phase detection system, and the optical pentaprism SLR viewfinder provides a traditional shooting experience. ISO sensitivity spans 100 to 800.

Burst shooting is supported at up to 3 frames per second. The body is constructed from polycarbonate with a metal chassis, weighs 700g, and measures 144 x 107 x 81 mm. Storage is via CompactFlash cards, and the 2.5-inch TFT LCD display resolves at 150,000 pixels.

A built-in pop-up flash with a guide number of 11 (ISO 100) is included, along with a standard ISO hot shoe. The BP-21 Li-ion battery is rated for approximately 500 shots per charge under CIPA standards. No video recording capability is listed in the specifications.

Color output supports both sRGB and Adobe RGB profiles.

Key Features — Sigma SD14

Foveon X3 APS-C Sensor: Captures full color data at every pixel across three stacked layers, unlike conventional sensors that interpolate color from a single-layer Bayer array.

14.1 Million Photodiodes: Three layers of 4.7MP each combine to record RGB information simultaneously, resulting in images with distinctive color accuracy and detail rendering.

TRUE Image Processor: Sigma's Three-layer Responsive Ultimate Engine processes the multi-layer sensor data to produce the final image output.

Sigma SA Lens Mount: Compatible exclusively with Sigma SA-mount lenses, keeping the system within Sigma's own optical lineup.

5-Point Phase Detection AF: Phase detection autofocus system with five focus points for reliable subject acquisition in typical shooting conditions.

Optical Pentaprism Viewfinder: Traditional SLR pentaprism viewfinder provides a direct, lag-free optical view of the scene.

Description — Sigma SD14

The Sigma SD14 is a DSLR built on the Sigma SA lens mount with an APS-C sensor that captures 14.1 million photodiodes across three layers, processed by the Sigma TRUE (Three-layer Responsive Ultimate Engine) image processor. Effective resolution is 4.7 MP at a native 2652 x 1768 pixels in RAW, with interpolated JPEG output reaching 4608 x 3072 pixels. Both sRGB and Adobe RGB color profiles are available.

Autofocus uses a 5-point phase detection system, and the optical pentaprism SLR viewfinder gives a classic DSLR shooting feel. Burst mode reaches 3 frames per second. The ISO range runs from 100 to 800.

A 2.5-inch TFT LCD at 150,000 pixels handles image review. The built-in pop-up flash carries a guide number of 11 (ISO 100), with a standard ISO hot shoe and wireless flash support also on board. The body weighs 700g, measures 144 x 107 x 81 mm, and is built from polycarbonate with a metal chassis.

Storage is via CompactFlash, and the BP-21 Li-ion battery is rated for approximately 500 shots per charge under CIPA conditions.
