The ACTAR-15 is an Ultra Wide Angle Lens, dedicated to the Cambo Actus system in combination with a dslr or mirrorless camera, mounted to the Actus. This lens is permanently attached to an Actus lens panel and has a focal length of 15mm. This makes it an ideal companion for interior, landscape and architectural photographers. With a relatively light weight and a modest size it is easy to carry with you to location shootings.

Use of the ACTAR-15 on the Actus with Fujifilm GFX 50/100 series is possible up to 6 mm of shift.
