The Sigma DP3 Merrill is equipped with the same 46MP Foveon X3 Direct Image Sensor as in the SD1 Merrill DSLR.
Compared to the previous Foveon sensor, this new generation has an expanded area matching the APS-C format (50% greater equivalent focal length). It also has a narrower pixel pitch, thereby dramatically raising the total pixel count.
In fact, we have achieved an extraordinary 46MP (4,800 x 3,200 x 3) effective pixels, triple the previous number.
This provides luminance resolution equivalent to that of a 30MP CFA sensor as measured on the standard B&W resolution chart used in conventional digital camera resolution testing.
With its much higher pixel count, the new Foveon X3 Direct Image Sensor realizes medium-format image generation capability, while retaining the “emotional image quality” unique to our full color capture system.
Sigma’s Dual TRUE II image processing engine was specially developed to process vast volumes of data at blazing speed, generating richly detailed images of amazing depth, which can be enjoyed even in large print formats.
Eye-opening sharpness. Natural edge definition. Finely graduated tonality … Here is a camera that redefines “high image quality” and invites you into a fresh dimension of visual experience.
The ‘Merrill’ name
Dick Merrill (1949-2008), co-developer of the revolutionary Foveon image capture system, was both a brilliant engineer and talented photographer. As an expression of Sigma’s passion for photography and in honor of Dick Merrill’s ability to realize artistic ideals through technology, we have named this new-generation sensor the “Merrill.”
