The Linhof Pro Compendium Lens Hood System M 679 consists of the filter holder, a normal bellows and a vignetting mask holder. The compendium is inserted into the optical bench on the M679 or M679CC camera, and is centered automatically. Vignetting blades are optional.
The filter holder mounts to the camera's accessory shoe. It accepts up to 2- 4x4" acrylic/glass filters, as well as an M105 x 1 screw-in filter.
The compendium consists of a small flexible self-supporting bellows. It insures the best possible exposures, with flare-free definition, contrast and color saturation.
