About
Sigma was founded in 1961 and remains headquartered in Kawasaki, Japan, with camera and lens manufacturing concentrated at its Aizu factory. The private company designs interchangeable lenses, mirrorless cameras and related optical equipment under its own brand. Its main market is photography and cinema rather than robotics, so the profile is intentionally limited to machine-mounted imaging applications.
Freefly is a verified downstream integration counterpart, using Sigma imaging hardware with aerial camera platforms. In that configuration, Sigma supplies the optical capture layer while Freefly provides stabilisation, aircraft integration and operational control. The relationship makes Sigma relevant to robotic cinematography and inspection payloads without implying that it develops autonomy software or purpose-built industrial vision systems.
