Cambo’s ACTAR-24 is a 24mm wide-angle lens, dedicated to the Cambo Actus series. Thanks to its design it will focus at infinity with mirror-less as well as DSLR camera bodies. On full frame 24×36 sensors, the optics allow for 10mm shifts. Using smaller sensors you may gain more shift, as the Actus offers more adjustments within the lens’ 60mm image circle. The optical design is built out of 16 elements, multi coated for high contrast.
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 (24×36) 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 electronic connections available nor needed.
