The use of Special Low Dispersion (SLD) glass accompanied by aspherical lens elements not only compensates for a variety of aberrations, but also allows for a more compact size.
Offering exceptional optical performance to provide minimal distortion and chromatic aberrations while suppressing ghosting and flare, the advanced lens unit allows for higher shutter speed and captures stunningly clear images.
It differs from its predecessor, the DP1x, because its lens now includes one "F" Low Dispersion glass element to correct aberrations, and its resolution has grown by moving from Foveon's 14.6-megapixel APS-C size image sensor to the 46-megapixel APS-C image sensor found in the company's flagship SLR, the Sigma SD1 Merrill.
