The Sigma SD1 is the first entry into high-end SLR market the company, and has accommodation of a magnesium alloy design, buttons and rubber O-ring ports, on time and farm dust. Body dimensions are 5.7 "x 4.4" x 3.1 "(145.5 mm x 113.5 mm x 80.0 mm) and weighs 24.7 ounces, the agency or 700 grams without battery and memory card.
Inside, the SD1 is a new APS-C size (23.5 x 15.7 mm) CMOS Foveon X3 image sensor is based. It's more important to some collectors "used in the past Foveon cameras, which have in the region of 20.7 x 13.8 mm. The factor of culture for the new chip is about 1.5 times, compared to a , 7 in the previous Sigma cameras.
The new sensor has an aspect ratio of 3:2, and provides images at 14.8 megapixels (4704 x 3136 pixels) - with a 78% increase in linear resolution than the previous generation of chips of Foveon Sigma SD15 DSLR in comparison. As with all the Foveon is the color information in each pixel, taken with the new chip with a total of just over 46 million effective photodiodes. More help with the sharpness of the pixels, Sigma does not use an optical low-pass filter in the Sigma SD1, because without a Bayer filter, the color moiré is not a problem. (Of course, the luminance moiré still possible with a sensor X3.) To handle all the additional data, the SD1, said a real couple II ("three-layer Responsive Ultimate Engine"), image processors, the same type may be used include, in the SD15, even if the device requires only a processor like this. With dual processors and DDR3 SDRAM memory buffer, the SD1 in a burst at full resolution up to 5 7 frames per second for RAW images, and can shoot RAW and JPEG simultaneously, a first for Sigma cameras.
On the first page, the SD1 has a Sigma SA bayonet with 40 goals Sigma SA mount. To help focus, a new Sigma 11-point type double cross said when autofocus sensor, with a working range of EV -1 to 18 rated at 100 ISO. Focus modes include both single and continuous with the predictive ability. AF points can be selected automatically or manually. Preview depth of field through a dedicated button.
For framing, the Sigma SD1, a pentaprism viewfinder with 98% coverage, 0.95x magnification e. SD1 is the researcher has a point 18 mm eye and -3 to 1.5 dpt provides a fix. The SD1 has a solid matte screen viewfinder and offers a superposition of development. On the back panel there is a 3.0-inch LCD viewing angle with 460 000 points wide to review the captured images.
The Sigma SD1 also features an integrated pop-up manual flash with a guide number of 11m and the coverage of 17mm. There are also synchronization with a PC and a terminal for external flash shoe, with the EM-140DG, EF-610 DG ST and EF-610 DG SUPER flash units. Determined by X-sync 1 / 180 second exposure and Sigma S-TTL flash. + / - 3.0 EV, flash exposure compensation is available in 1 / 3 EV.
Designed for professionals and amateurs who display options Sigma SD1 include not only offers scene modes and Program AE (Program Shift), offer the aperture priority, shutter priority and manual mode, if the face has three parameters can be recovered quickly. Sigma SD1 exposure system has four modes: 77-segment multi-zone, center-weighted, center weighted and spot metering with a working range of EV 1 to EV 20 (50 mm f/1.4 lens at ISO 100). ISO equivalent sensitivity range of 100-6400 and shutter speeds from 1 / 8000 to 30 seconds, including a bulb mode, up to two minutes may be extended.
The Sigma SD1 records images on CompactFlash Type I and its compatible UDMA CF slots. Does not support Type II cards, Microdrive. Power is derived using a single BP-21 Lithium-ion or plug optional PG-31, which can hold two BP-21 batteries. No word yet on battery life.
The Sigma SD1 does not seem to offer a live view or video recording capabilities. However, the Sigma SD1 looks like a big step forward for the company based unique Foveon DSLR range, and is likely to be of great interest to fans of X3 sensors.
MSRP for the Sigma SD1 is U.S. $ 9,700, even if road pricing is less likely. Availability begins in early June 2011.
