Manufacturer description

The МС ГРАНИТ-11Н 4,5/80-200 photographic lens is intended as an interchangeable lens for КИЕВ-17, КИЕВ-19 and КИЕВ-20 small format cameras.

The МС ГРАНИТ-11Н is a 2.5x zoom covering the range of focal lengths of the most commonly used telephoto lenses. In the process of shooting, it provides the ability to select any focal length in the range of 80-200 mm. Thanks to this, you can accurately position the photographed object in the frame without moving the camera to another shooting point, which is especially important when working with reversal film.

The lens has a special multi-layer coating that improves image quality and enhances its contrast by increasing integral transmission and reducing scattering.

When changing the focal length, the sharpness of the picture is preserved.

The lens is equipped with a device for automatic setting of a pre-selected aperture value, which allows for viewing and focusing with the aperture fully open. The device is kinematically connected to the camera and is triggered by pressing the camera release button.

The lens is relatively small in size, lightweight and convenient for handheld shooting.

The lens operates in a temperature range from -15 to +45° C.

From the "СОВЕТСКОЕ ФОТО" (No. 11, 1985)

The Arsenal Plant Production Association has developed the eleven-element variable focal length lens МС Гранит-11Н, designed for the small-format SLR cameras Киев-17, Киев-19, Киев-20. The lens is based on the Гранит-11 lens, but has a number of advantages over it: a "jumping" diaphragm, automatically set when the shutter release button is pressed, multi-layer coating of optical elements, which allows increasing the transmission coefficient by 15%, reducing the light scattering by 40% and improving color rendition (color formula - 11-0-0). The resolving power of the lens is very high: not less than 50mm^-1 at f=80mm. All this ensures high-quality images (high contrast, correct tone rendition, clear detail elaboration).

From the editor

The lens was produced by the Arsenal Plant (USSR). After the collapse of the Soviet Union, the lens was sold under the name "ZOOM ARSAT H 1:4.5 80-200mm".

Light transmission: 0.80. Resolving power, mm^-1: f=80mm: at the center of the field: 50, at the edges of the field: 20; f=150mm: at the center of the field: 36, at the edges of the field: 20; f=200mm: at the center of the field: 45, at the edges of the field: 20.
