For many years Canon has established a reputation for manufacturing high quality lenses for both consumer and professional photographic use. These include an extensive range of large format long focal length telephoto lenses with direct motorised iris and focus where the focusing motor is mounted in the lens assembly itself. They require the use of Canon cameras with the specialised EF (electro focus) lens mount developed by Canon. Traditionally, the majority of machine vision cameras feature comparatively small image sensors and utilise fittings for the smaller C-mount and CS-mount lenses. At the high end, although large format lenses have been used, they have been limited to non motorised applications with fixed focal lengths up to 100mm.
