Quelques images du futur Sigma SD1.
A noter :
- Le Sigma SD1 utilisera le nouveau (futur ?) capteur Foveon à 48 MP
- Il comportera un filtre contre la poussière qui ferme toute la cage miroir
- Écran LCD de 3″ à 420.000 pixels
- Système AF à 11 points
- Viseur optique reflex à couverture de 98%
- La quasi-totalité du boitier est construite en alliage de magnésium avec une belle monture d’objectif en acier
Noter aussi l’absence totale d’enregistrement vidéo !
Il arrivera avec quelques nouveaux objectifs et un flash :
- Sigma 150mm F2.8 Macro
- Sigma 120-300mm F2.8
- Sigma EF-610 DG flash
The Sigma Corporation is pleased to announce the new SIGMA SD1 Digital SLR Camera, incorporating a 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor.
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 a weather-resistant design throughout for use in harsh conditions.
The SIGMA SD1 incorporates a 24×16mm 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 color.
The SD1 is SIGMA’s latest digital SLR camera which meets high requirements of professional and enthusiast photographers for all types of photography.
This product is showcased at Photokina 2010 in Koln, Germany.
SIGMA SD1 Product Summary
46 megapixel 24×16mm APS-C X3 Full-color image sensor
The 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor featured in the Sigma SD1 captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. 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 color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moire is not generated, the use of a low-pass filter is not required, meaning light and color, 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.
The SD1 adopts the TYPE I CF Card. This camera is compatible with the UDMA enabling fast processing of large amounts of data.
* It is not possible to use Microdrives and TYPE II CF cards.
11 point twin cross sensor
The autofocus system features an 11 point twin cross sensor. The shifted twin cross type sensor improves AF accuracy.
The Sigma SD1 adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions.
Buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body.
Large, highly visible 3.0” TFT color LCD Monitor
The SD1 camera features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.
The SD1 can be used with over 40 Sigma lenses such as ultra-wide, ultra-telephoto, macro and fisheyes which adopt the latest technology such as the FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, SLD glass, Aspherical lenses, Sigma’s own unique Optical Stabilizer function, Hyper Sonic Motor and Sigma’s Super Multi Layer Coating. They meet the various and demanding requirements of all types of photographers.
