This ACTAR-19 Ultra Wide-Angle Lens is 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 19mm. 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.
The ACTAR-19 is a lens with almost no geometrical distortion. As the image circle is over 71mm, there is an optically allowed 15mm horizontal shift possible on each side when using a full frame (24 x 36) sensor in landscape mode, and 18mm in portrait mode. Use of the ACTAR-19 on the Actus with FUJIFILM GFX 50/100 series is possible with at least 9mm of shift. When using a digital back with a sensor-activated electronic shutter on the Actus-DB or XL, the image circle will cover a sensor size of 54 x 41.
The optical design features 17 elements in 13 groups, including elements with a Nano Crystal coating. The aperture range is from f/4 to f/32 in half-stop increments. Please note that the aperture is manual and electronic connections are not needed.
