The ACTAR-24 is, like most wide-angle lenses, relatively sensitive for environmental light, direct as well as indirect light. For this, Cambo has developed a compendium lens hood, dedicated to this wide-angle lens.
The hood is flexible and self-supporting. It can be pulled out to 80mm extension and folded backward enough to clear the edges from vignetting when using movements.
The hood slips over the 100mm diameter of the front of the lens and attaches with one synthetic thumbscrew.
Basically, this lens hood is compatible with any lens with a front diameter of 100mm, which also includes the Rodenstock HR-W 32mm, as used in several combinations with other Cambo products.
