Rehousing Company
Company Website: http://www.dk-optic.com

DK Optic (also referred to as DK Optik or DK Optics) is a China-based rehousing company focused on the mechanical reconstruction of vintage photographic and cinema lenses—particularly the Canon FD series—for modern professional use. Unlike traditional manufacturers, DK Optic does not design or produce optical elements. Instead, they specialize in transforming classic lenses into robust, cinema-grade tools by engineering new housings with features such as cam-based focus systems, uniform front diameters, and PL mount conversions. Known for their affordability and accessible design. DK Optic shares their technology and space with Illuvision Co. - another lens rehousing outfit.
