The ACTAR-20 is an Ultra Wide Angle Lens for the Cambo Actus system. It can be used with Mirrorless camera bodies or Digital Backs (On Sensor shutter only). This lens is permanently attached to an Actus lens panel and has a focal length of 20mm. This, and its relatively light weight and modest size, make it an ideal companion for interior, landscape and architectural photographers. This new Actar-20 does have a 82mm filter thread.

The ACTAR-20 is a lens with almost no geometrical distortion. As the image circle is 68mm, there is an optically allowed horizontal shift possible of 17mm each side when using a full frame (24x36) sensor in landscape mode, and 14mm in portrait mode. Use of the ACTAR-20 on the Actus with Fujifilm GFX 50/100 series is possible up to 8 mm of shift.

The optical design of this lens is a 16 element in 11 groups. The aperture range is from f/4,0 to f/22 in half stop increments. Please note that the aperture is manual and there are no electronical connections available nor needed.
