Lenses. Three lenses of different focal length are provided for use on the 16 mm camera.
10 mm. A medium wide-angle lens, the field of view being 41.1 degrees x 54.9 degrees.
It is used for internal crew activities and equipment when details are required. Focus is from 6 inches to infinity with aperture openings from f 1.8 to 22. It has two spike-like handles for setting f-stop and distance with the gloved hands.
18 mm Kern. A lens of slightly wide-angle design and high optical quality. Primary use is for vehicle-to-vehicle photography while bracket-mounted at left or right rendezvous window. It is also the widest angle lens that may be used with the right-angle mirror.
This lens is usually stowed on the camera. Viewing angle of 24 x 32 degrees and weight is approximately 0.80 pound and has two spike-like handles for setting the f-stop and distance with the gloved hand. This improved lens has larger numbers for reading while in the EV spacesuit.
75mm Kern.
Думается мне, что это многое меняет. И аФонины 3,41 градуса благополучно превращаются в 1,86, и, соответственно расстояние до LRV когда он попой к камере будет 55,4 м безо всяких натяжек.
