Description — Cambo ACTAR-19
The Cambo ACTAR-19 is a 19mm prime lens built for the Actus modular technical camera system. It mounts via a Lens Board (Technical Camera) interface, making it a natural fit within the Cambo Actus ecosystem. With an ultra wide-angle field of view and a maximum aperture of f/4, the ACTAR-19 is suited to photographers who need a very short focal length for their Medium Format work.
The lens is classified under the Large Format lens format and operates entirely in manual focus mode — there is no autofocus, and no image stabilization is present. As a prime lens, the focal length is fixed at 19mm, with no zoom range. The ACTAR-19 is a purpose-specific optic for technical camera shooters who demand a dedicated ultra-wide option within the Actus system.
