The ACTAR-24 /X2 is a lens dedicated to the Cambo X2-Pro in combination with a dslr or mirror less camera, mounted to the X2-Pro. This lens is permanently attached to a X2-Pro lens panel and has a focal length of 24mm. This makes it an ideal companion for 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-24 is a lens with almost no geometrical distortion. As the image circle is 60mm, there is an optically allowed horizontal shift possible of 10mm each side when using a full frame (24x36) sensor in landscape mode, and 12mm in portrait mode. When using a smaller APS-C sensor the shift possibilities grow to 15mm and 17mm. Of course vertical shifts have the same possible numbers in reverse order.
The optical design of this lens is a 16 element in 11 groups, of which all lenses are multicoated to achieve the best contrast. The aperture range is from f/3,5 to f/22 in half stop increments. Please note that the aperture is manual and there are no electronical connections available nor needed.

When used in combination with a 24x36 chip the following
perspective comparison applies:
= 24 mm on SLR full frame
= 35 mm on 48x36 digital back CCD
= 40 mm on 4,5x6cm film size
= 75 mm on 4x5" film size
