The structure's cone-like shape was designed to reduce wind turbulence, yet there is only one piece of curved glass on the building: a lens-shaped cap at the very top.
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.
Here, the 808 PureView delivers again with an autofocus prime lens made by Carl Zeiss that features five aspherical glass elements (in one group) and a mechanical shutter.
