The Sigma SD15 is the latest model in Sigma's SD series of digital SLR cameras. Powered by the 14 megapixel Foveon X3 direct image sensor, the SD15 can capture all primary RGB colours at each and every pixel location arranged in three layers. In order to get the best out of the Foveon X3, the SD15 also incorporates the TRUE II image processing engine which processes the large amount of data from the 14 megapixel direct image sensor. In addition it provides high resolution power and reproduces high definition images with impressive three-dimensional detail, rich in gradation. The Sigma SD15 uses the convenient SD memory card format and incorporates a highly visible 3.0 inch LCD monitor, 77-Segment AE sensor and AFE (Analogue Front End). It provides high image quality and user friendly design. In addition, the durable shutter mechanism, which has a life of over 100,000 actuations, is ideal for the demands of digital photography. The Sigma SD15 Digital SLR Camera is a different way of thinking.
SD15 Digital main features
14 Megapixel Foveon X3 direct image sensor
The Foveon X3® direct image sensor captures all primary RGB colours at each and every pixel location. As the photo detectors are arranged in three layers, full and complete colour is captured giving the images a three-dimensional feel.
Durable focal plane shutter
The durable focal plane shutter mechanism has a life cycle of over 100,000 exposures and dramatically reduces the amount of dust and dirt from the shutter mechanism. The photographer can enjoy taking pictures without worrying about dust and dirt adhering to the image sensor either from inside or outside the camera.
Two motor systems for prevention of camera shake
The two motor systems are driven by the mirror-drive and shutter charge which lowers the vibration of the mirror movement, preventing camera shake. The mirror lock-up mechanism raises the mirror, preventing further vibration when the shutter is released. The prevention of camera shake is especially effective for macro photography and when using ultra-telephoto lenses.
Improved buffer memory
The SD15 is equipped with DDR II buffer memory which is twice as large in capacity as the SD14's buffer. The camera's high-speed image processing circuits are capable of handling the large data files generated by the high-resolution 14 megapixel sensor. The SD15 features a continuous shooting speed of 3 frames per second with up to 21 RAW Images that can be captured in continuous shooting mode.
TRUE II image processing engine
The SD15 incorporates the TRUE (Three-layer Responsive Ultimate Engine) II" image processing engine which improves the processing speed and overall image quality. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones. The improved processing speed of RAW and JPEG data provides ease of camera operation.
SD memory cards for added convenience
The SD15 adopts the SD card (compatible with SDHC) which is also used in the DP series of Sigma cameras improving convenience to users of both camera systems.
AFE (Analogue Front End) - Improving performance at high sensitivity
AFE (Analogue Front End) converts the colour data, which full-colour capture systems record, to a digital signal. This enables the camera to reproduce high definition and richly coloured images.
ISO 50–3200 - Providing noiseless image processing
The SD15 captures light effectively and ensures noiseless image processing. The image sensor provides high definition with rich, gradated tones.
Fast and precise focusing with 5-point AF
The auto focus sensor features 5 focusing points (centre, left, right, up and down) ensuring consistently fast and precise focusing. The AF metering features a cross type sensor in the centre of the screen. Selecting the AF point can be done manually or automatically.
Five frame Auto Bracketing function
In addition to the usual three frame bracketing, five frame bracketing has now been added to the Auto Bracketing function. It allows users to get a more detailed and accurate exposure.
Bright viewfinder image by the incorporation of a pentaprism
The SD15 features a pentaprism viewfinder with 98% (vertical and horizontal) coverage, 0.9x magnification and an 18mm eye point. A dioptre adjustment is also equipped which can be adjusted from -3 to +1.5 dpt.
Exposure compensation function
It is possible to adjust the camera's measured exposure value. When it is difficult to determine the exposure setting due to variable light conditions, it is possible to take a sequence of pictures of the same subject at three or five different exposure levels. The shift value can be set in 1/3EV increments up to +-3EV(3 stops) / +-1.7EV(5 stops).
77-Segment AE Sensor
The SD15 features a new 77-segment AE sensor which allows advanced AE algorithms, improving exposure accuracy. Exact control and collaboration with the AF point ensures the camera exposes accurately even in difficult lighting conditions.
Most digital SLR cameras are vulnerable to dust entering the body. If the dust and dirt adhere to the image sensor, it may appear in the pictures. The mount of the SD 15 is equipped with a dust protector and the sealing parts are incorporated around the mount, preventing dust from entering the body. Even if dust adheres to the image sensor, the dust protector can be removed easily for sensor cleaning.
Simple user interface for faster camera operation
The improved user interface provides faster and more convenient operation of the camera. The Quick Set button activates the display of the most commonly used camera functions such as Colour Mode, White Balance, Image Quality and Image Size on one screen. The 4-Way Controller ensures faster operation of these features. The FUNC button enables functions such as Flash Mode and Synchro Mode.
Large 3.0” TFT Colour LCD Monitor
The SD15 camera features a 3.0 inch TFT colour LCD monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.
OK Button setting
It is possible to allocate certain functions to the OK button for added convenience. These functions include Review image, Rotate Image and Mark Image.
Built-in flash with 17mm angle of coverage
The Sigma SD15 camera's built-in flash offers an angle of coverage of 17mm (equivalent to 28mm with a 35mm camera) lens with a guide number of 11. The Built-in flash can be synchronised to a shutter speed up to 1/180 sec. Incorporation of S-TTL automatic exposure system ensures the control of advanced flash photography.
Backlit top LCD panel
The top LCD panel allows the photographer to quickly check camera information such as the resolution setting, metering mode, battery status and the number of images that can be recorded on the SD card. It also incorporates an orange backlight which enables the camera to be easily controlled in low light conditions.
SIGMA Photo Pro 4.0
The supplied image processing software of SIGMA Photo Pro 4.0 converts RAW data quickly and easily. Incorporation of a new noise reduction algorithm reduces chroma and luminance noise. In addition, it is compatible with five Colour Modes which apply a suitable setting to each shooting situation. The adjusted settings can be saved to the RAW file.
Dedicated rechargeable battery with a large capacity
Back to top
The dedicated BP-21 Lithium-ion battery is supplied as standard with the SD15. It is possible to shoot approximately 500 images on one full charge and takes about 120 minutes to fully charge with the supplied BC-21 Battery Charger. The optional AC Adapter SAC-4 enables the Sigma SD15 to obtain power from the main supply.
