The ACTAR-19 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 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 68mm, there is an optically allowed horizontal shift possible of 12mm each side when using a full frame (24x36) sensor in landscape mode, and 14mm in portrait mode. Use of the ACTAR-19 on the Actus with Fujifilm GFX 50/100 series is possible with at least 5mm of shift.
Also, when using a digital back with sensor activated electronic shutter on the Actus-DB or XL, the image circle will cover the sensor.
The optical design of this lens is a 17 element in 13 groups, including elements with Nano Crystal Coat. The aperture range is from f/4 to f/32 in half stop increments. Please note that the aperture is manual and there are no electronical connections available nor needed.
