Three hundred percent: that’s the difference between Sigma’s latest flagship medium-format camera, the SD1, and its predecessor, the SD15. With 46-megapixel resolution (three layers of 15.3-megapixel Foveon X3 sensor cards), Sigma is blazing trails with this particular model.
Scheduled to be released in June, the SD1 is housed in a weather- and shock-resistant magnesium alloy body.
To handle these large-resolution files, Sigma has included two TRUE II image processors in the body. The SD1 will capture up to 7 frames per second with its 11-point autofocus sensor and has an ISO sensitivity range from 100 to 6400. Like many high-end DSLR cameras, the SD1 has two control wheels and a 3-inch TFT color monitor. Users can shoot RAW files in full-, half- or quarter-size format.
Not surprisingly, the increase in sensor quality comes with an increase in price, although Sigma is advertising this camera as more affordable than comparable brands.
Sigma is offering four different kit options with the SD1 body, ranging in price from $7,539 to $8,649, depending on the accompanying lens. Current kit options include either an 85mm f/1.4 EX DG HSM, 17-50mm f/2.8 EX DG HSM, 24-70mm f/2.8 EX DG HSM, or 30mm f/1.4 EX DG HSM lens.
