Sinar Photography AG is a Swiss company based in Zurich manufacturing specialized high-resolution view cameras for studio, reproduction, landscape and architecture photography.
Sinar's view-cameras allow both the lens and the film back or sensor back to move in rotation or linearly in any direction (up/down, left/right, front back linearly, and pitch yaw tilt rotations), thus allowing precise image alignment corrections. The cameras are thus often used in advertising, document reproduction, product and architectural photography, where correctly vertical image lines, fine focus accuracy, and extra details are wanted.
The name SINAR is explained by the company itself as "Still, Industrial, Nature, Architectural and Reproduction photography" in the English version of the April 2011 press release. Other versions of the names were also used, with the S for studio, sach, or science.
