About Sigma SD1

This Sigma SD1 Bundle comes with: and Shipping is free! .

Professional and high-end enthusiast photographers will utilize the Sigma SD1's exclusive Foveon 23.5x15.7mm APS-C X3 direct image sensor to capture exceptionally rich and detailed images that have a film-like quality. Users will also benefit from Sigma's wide selection of interchangeable lenses that are compatible with the SD1.

The Sigma SD1 features dual "Three-layer Responsive Ultimate Engine (TRUE) II" image processing engines, which improves processing speed, provides high resolution power and produces high-definition images with richly graduated tones. It also allows simultaneous RAW and JPEG recording, which is a first for Sigma cameras. Additionally, the photographer has the option to select full-size, half-size or quarter-size RAW files making it a more versatile camera for a wide range of photographers. The Foveon sensor uses 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. This technology efficiently reproduces color more accurately and offers sharper resolution, pixel for pixel, than any conventional image sensor.

The optical format of the Foveon sensor has been upgraded from that which was used in previous SD cameras and has increased from 1.7x focal length to the 1.5x focal length multiplier. The SD1 also benefits from improved image processing and noise reduction algorithms, with an ISO sensitivity range from 100 to 6400. This is two full stops more sensitivity than the SD15, which has a maximum 1600 ISO. An intuitive user interface and an impressive lightweight, yet solid magnesium alloy body and O-ring sealing connections that make the camera durable and splash proof are also key feature upgrades of the flagship SD1.

The SD1 adopts the TYPE 1 Compact Flash Card and is UDMA-compatible enabling fast processing of large amounts of data. The autofocus system features an 11-point shifted twin cross type sensor, which improves AF accuracy. The SD1 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 more than 40 Sigma SA mount lenses such as ultra-wide, ultra-telephoto, macro and fisheye.

Sigma's image processing software, Photo Pro 5.0, comes bundled with the camera and its simple operation allows quick and easy capture of the desired imaged. Additional functions such as Loupe, Slideshow, Print, Convert to JPEG file and Batch White Balance settings are also incorporated into this software.

Sigma SD1 Reviews

A disappointment for a top of the line..


from los angeles ca  -  Photo Enthusiast

I tested sigma camera SD1 for one day and battery lasted for only 90 shots first charge 72 shots the second charge.(about 73 degrees outdoors) has interesting buffer design 2 or 3 buffers. Indoor portrait photos were below expectations in color and b and w I give it no star (that bad (quality). My small kodak(digital) camera ($159.00) takes much better pictures (indoor portraits) with same conditions for indoor (natural lighting etc.)both cameras using no flash and with camera flash... will check studio set up style lighting later. SD1 takes only 10 megapixel b&w (disappointing) no pro adjustments (picture) like Nikon, canon, sony. No live view and video recording (1080 HD) also. I recommend demo camera in camera store take pictures(inside store) and check results before buying.. returning it is a lot of trouble. I tested 17-50mm f2.8 sigma probably will be disc. soon has angular distortion on linear perpendicular at 17mm to 30mm (maybe manufacture defect.) or engineering design (sigma has no level indicator in viewfinder) like some other manufactures but lens seems to have good dep of field and at 2.8 good bokeh effect but lens is sharp. I try a 70-300mm apo sigma and photo's were TOTALLY unacceptable (just like what p. photo said)lens seem sharp but picture quailty is really bad.(no star for all types of photography) but sigma claims at web site different autofocus design is used for that lens (okay but manual focus is also totally unacceptatble picture quailty) similar to what magazine said so buyer beware for sure. test demo camera to be sure.

sucker born every day.


from new castle, de.  -  Photo Enthusiast

figured with the layer three colored system I could hopefully convert to black and white with better contrast and quality over the bayer system; shutter hesitation, even with 3 batteries I could not get more than 60 shots on each battery.Sigma service was no help. Said camera and battery was o'k. 3k investment was wasted. No Sigma ever again. Donated camera, flash, lense & 3 batteries. I'll stick with other camera companies ( Nikon) that understand what a service dept, is for. photo enthusiast since 1955.
