Sigma heeft de uiteindelijke adviesprijs en de beschikbaarheid van de in september 2010 aangekondigde SD1 bekend gemaakt. De camera komt vanaf juni op de markt voor een adviesprijs van € 6.950 (ter vergelijking: de Amerikaanse prijs is $ 9.700). De camera beschikt over de vernieuwd Foveon sensor met 46 megapixels (bestaande uit drie lagen van 15,3 megapixels). Sigma richt zich met de camera op professionele fotografen, waarbij de SD1 een alternatief voor middenformaatcamera’s moet vormen.

46 megapixel 24×16mm APS-C sensor
Lightweight yet solid magnesium alloy body
Weather-resistant O-ring sealing connections
Dual ‘TRUE II’ image processing engines
11 Point Twin Cross AF Sensor
Sigma Imaging (UK) Ltd is pleased to announce that the suggested retail price of the new SD1 flagship digital SLR is £6,199.99 including VAT (£5,166.66 excluding VAT). This new camera, offering unrivalled image quality amongst digital SLRs, will be available in the UK in June.
The SIGMA SD1 is Sigma’s flagship digital SLR model, adopting a lightweight yet solid magnesium alloy for its body and O-ring sealing connections to make Sigma’s splash proof design throughout for use in harsh conditions.
The SIGMA SD1 incorporates a 23.5×15.7mm APS-C X3 direct image sensor and dual “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engines. The combination of the 46 megapixel (4,800×3,200×3 layers) sensor and dual TRUE II processing engines ensure the high resolution images are processed quickly with high definition and a smooth and subtle graduation of colour.
46 megapixel 23.5×15.7mm APS-C X3 Full-colour image sensor
The 46 effective megapixel (4,800×3,200×3 layers) and 44 recording megapixel (4,704×3,136×3 layers) 23.5×15.7mm APS-C X3 direct image sensor featured in the Sigma SD1 captures all primary RGB colours at each and every pixel location, ensuring the capture of full and complete colour. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths, it efficiently reproduces colour more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since colour moiré is not generated, the use of a low-pass filter is not required, meaning light and colour, generated by the 46 megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.
Dual TRUE II image processing engine
The SD1 incorporates a dual “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engine which improves the processing speed and overall quality of the final image. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones. In addition, the SD1 is Sigma’s first camera to allow simultaneous RAW and JPEG recording.
Advanced DDR III buffer for high-speed, high-volume data processing
To handle large volumes of colour data at high speed, the SD1 uses DDR III buffer memory technology, which delivers class-leading performance. The SD1 features a continuous shooting speed of 5 frames per second and can capture up to 7 RAW images per sequence in continuous shooting mode.
The SD1 adopts the TYPE I CF Card. This camera is compatible with the UDMA enabling fast processing of large amounts of data.
Intuitive user interface
The improved user interface provides faster and more convenient operation. Aperture and shutter speed can be set by their own dials. The exposure compensation button and exposure mode button are on top of the body for quick access. A Quick Set (QS) menu lets you easily change commonly used functions. To display the QS menu, simply press the QS button. QS menu 1 is for ISO setting, flash mode, metering mode and AF mode; QS menu 2 offers white balance, image quality, image size and colour mode.
The Sigma SD1 adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions.
Splash proof design
Buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body.
Bright, wide-coverage viewfinder with integral pentaprism
The SD1 features a pentaprism viewfinder with 98% (vertical and horizontal) coverage, 0.95x magnification and an 18mm eye point. Diopter adjustment is provided over a range of -3 to +1.5 dpt.
The SD1 features four metering modes
The SD1 features 77-segment Evaluative Metering, Centre Weighted Average Metering, Centre Area Metering and Spot Metering. Exposure can be manually adjusted to suit your needs. When difficult lighting conditions make appropriate exposure unclear, auto bracketing lets you take a sequence of shots of the same subject at three or five different exposure levels. Bracketing can be set in 1/3EV increments up to +-3EV(3levels) or +-1.7EV(5 levels).
11 point twin cross sensor
The autofocus system features an 11 point twin cross sensor. The shifted twin cross type sensor improves AF accuracy.
77-segment AE sensor for accurate exposure
The SD1 features a new 77-segment AE sensor using advanced AE algorithms to improve exposure accuracy. Exact control coordinated with the 11 AF points achieves accurate exposure even in difficult lightning conditions.
Most digital SLR cameras are vulnerable to dust entering the body. If dust and dirt adhere to the image sensor, it may appear in the photos. The lens mount of the SD1 is equipped with a dust protector and the area around it is sealed to prevent dust from entering the body. Even in the unlikely event of dust adhering to the image sensor, the dust protector can be removed easily for sensor cleaning.
Focal Plane shutter
The durable focal plane shutter mechanism has a life cycle of over 100,000 exposures and dramatically reduces generation of dust. The photographer can enjoy taking pictures with confidence that the image sensor is clean and protected from dust or dirt originating inside or outside the camera.
Two-motor system prevents vibration
Using a two-motor system with dedicated motors for mirror-drive and shutter charge reduces the vibration of mirror movement, thereby preventing camera shake. A mirror lock-up mechanism prevents further vibration when the shutter is released. Preventing camera shake is especially important for macro photography and when using ultra-telephoto lenses.
ISO100 – 6400. Noiseless image processing
ISO sensitivity can be selected from 100 to 6400. The SD1 captures light effectively and ensures noiseless image processing. The image sensor provides high definition with rich, graduated tones.
Large, highly visible 3.0” TFT colour LCD Monitor
The SD1 camera features a 3.0 inch TFT colour monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.
Built-in flash with 17mm angle of coverage
The Sigma SD1 camera’s built-in flash has a guide number of 11 to cover a 17mm lens angle (equivalent to 25.5mm with a 35mm camera). The built-in flash can be synchronized to a shutter speed of up to 1/180 sec. The S-TTL automatic exposure system enables control of advanced flash photography.
SIGMA Photo Pro5.0 (Supplied)
The supplied image processing software, SIGMA Photo Pro 5, converts RAW data quickly and easily and describes full data of 460,000 pixel resolution. A renewed interface design provides functional and convenient operation. Sigma PhotoPro allows easy operation, simply by moving a slider from left to right while looking at the particular image you took, you can get a photographic expression just as you like. In addition, other functions such as Loupe, Slideshow, Print, Covert to JPEG file and Batch White Balance settings are incorporated into this software.
