Beginning in September 1979 it was also installed in utility/agricultural aircraft, such as the Antonov An-2 for terrestrial surveys and recordings. A total of eleven MKF-6 cameras was produced. A completely revised version of the device, the MKF-6M, that could be remotely operated from the ground was introduced in 1978 and deployed at the Salyut programme of Salyut 6 and 7 and the MIR space station. The spacecraft was modified and equipped with a module that accommodated the camera. The MKF-6 was first used in September 1976 on board of Soyuz 22. The geoscientific flight test program, developed by the Central Institute for Earth Physics (Zentralinstitut fГјr Physik der Erde) took place aboard Soviet military aircraft. The PKA precision copying machine was designed for image reproduction. With it, several spectral images, on top of each other and under various filters can be projected on a screen or photographic film.

Parallel to the MKF-6, a multispectral projector, the MSP-4 was developed. Thus, the lens frames could be reworked with highest accuracy and then arranged in tubes of precise interior diameter. The mounted lenses were centered in such a way that the axis of rotation of the machine and the optical axis of the lenses matched exactly. Each of the lenses was framed separately and then clamped in a purpose-built lathe. Manufacture of the lenses was also very complex. Moreover, the camera moves in the flight's direction during exposure to compensate for the carrier satellite's or spacecraft's orbital movement and speed of approximately 20.000В km/h (12.427В mph), which otherwise causes smearing and blurry images. In order to acquire the desired quality, the developers of Carl Zeiss Jena created a completely new lens type.

Nevertheless, all photos of all lenses have to be free of optical distortions and require an identical image scale regardless of their spectral range. ДЇilms and filters can be variously combined.

The MKF-6 is equipped with six high-resolution Pinatar 4.5 / 125 mm (focal length) lenses and a rotary shutter, capable to simultaneously take six photos in six different spectral ranges at an exposure time between 1вЃ„ 20 and 1вЃ„ 200 seconds. The total weight of the camera including all its control units doesn't exceed 175В kg (386В lb).

An overlay of 20 to 80% of the images was possible for serial recordings. 70В mm (2.8В in) wide un-perforated films with a length of 110 to 220В m (360 to 720В ft) (depending on the thickness of the film) per lens were used, which provided individual images with a Negative format of 56 by 81В mm (2.2 by 3.2В in). With the MKF-6, terrain sections of around 225В km (140В mi) length and 155В km (96В mi) width, at a flight altitude of 355В km (221В mi) and a resolution of about 10 to 20В m (33 to 66В ft) (in the visible range) were recorded.
