     "Krasnogorsk-2", 1966-1977 gg.     Cinematographic apparatus is designed for the shooting of films on 16mm color and black and white film with single-sided or double-sided perforation.
     The maximum frame size - 10,2 × 7,6 mm.
     Recording frequency - 8, 12, 16, 24, 32 and 48 frames / sec.
     Charging system - cassette, the cassette of the film stock - 30 m
     The lens "Meteor-5-1" with a variable focal length of 17 mm to 70 mm and a relative aperture - 1:1.9.
     Drive system - a spring, one platoon provides drawing at least 5 m of the film.
     Adjusting the exposure - with the help of semi-automatic exposure meter running through the shooting lens in the range of sensitivity of the film from 8 to 250 units of GOST.
     Obturator - bilobed mirror with the opening angle of 150 ° (2 × 75 °).
     Reticle - parallax, working through the shooting lens. The increase in the viewfinder - 10x
     Diopter eyepiece - ± 5 diopters.
     Weight (without case and accessories) - about 3.0 kg.
     A total of 15080 made such cameras.
     Issue I - Camera Black
     Issue Ia - camera gray
     The main elements of a semi-automatic aperture setting are: galvanometer with an arrow, photo resistor to regulate current in the galvanometer, depending on the brightness of the subject, and mercury oxide battery of two elements of the RC-53 to power the circuit.
     Filming unit operates at frequencies of six shooting, as well as time-lapse photography of the cable release. The normal frequency of shooting - 16 frames per second. Furthermore, the apparatus provides a slow filming or frequency 8 to 12 / s and increased at 24, 32 or 48 frames / sec.
     When shooting with a slow rate of movement on the screen will be faster in 1.5 or 2 times.
When shooting at 24, 32, or 48 frames / sec on the screen will move slower, respectively, 1.5, 2 or 3 times.
Each frequency corresponds to a certain shooting shutter speed (see table).

     The frequency of shooting a / s 8 12 16 24 32 48
     Exposure, sec 1/19 1/29 1/38 1/58 1/76 1/116

     The complete unit includes filters GS-17, GS-12, GS-10 and HC-4x.
Yellow filter GS-17 eliminates the effect of atmospheric haze, enhances the contrast of distant objects, and allocates the cloud increases the contrast in the shadows. Correcting filter GS-12 improves the tone reproduction in natural light and is used in the filming of genre scenes and portraits of the visual brightness of blue, green and yellow objects. GS-10 filter reduces the influence of ultraviolet rays, is used to overcome the impact of the weak aerial haze when filming landscapes. The neutral density filter HC-4x is used in cases when the brightness of the subject is very high and the arrow galvanometer can not be combined with cut-frame viewfinder even with full lens diaphragm.
