Manufacturer description

The КИЕВ-20 is a small format SLR camera of the TTL system with semi-automatic exposure metering. Designed for amateur photography.

Designed for 35mm wide photographic film in standard cassettes.

The КИЕВ-20 is available with МС ГЕЛИОС-81Н lens (aperture limits 2-16, focal length 50mm, relative aperture 1:2) or МС ВОЛНА-4Н (aperture limits 1,4-16, focal length 50mm, relative aperture 1:1,4).

The lenses have a special multi-layer coating, as indicated by their marking (МС).

Multilayer coating improves image quality and increases its contrast by increasing the integral light transmission and reducing lens scattering.

The lens mount is of a bayonet type.

The design of the camera provides for the use of interchangeable lenses, specially produced for КИЕВ-17 and КИЕВ-20 cameras. Interchangeable camera lenses of the NIKON camera can also be used.

The curtain metal shuter provides speeds in the range of 1/1000 - 1 s and "B". The curtains move along the short side of the frame from bottom to top.

The Fresnel lens and condenser lens in the viewfinder provide increased brightness and thus make it possible to shoot in low light conditions. Matte glass of the viewfinder covers 93% of the frame area.

Focusing is carried out using a wedge, a microraster ring and ground glass.

The shutter cocking mechanism is interlocked with the film transport mechanism. If double exposure is needed, the film transport mechanism can be disabled.

The frame counter is automatically set to the starting position when the back is opened.

The camera's exposure meter determines exposure based on the light passing through the lens. The advantages and convenience of the TTL measurement system is that it automatically takes into account all factors influencing the exposure value (field of view of the lens, its light transmission, etc.).

The exposure meter provides measurements in the brightness range from 1.6 to 13,000 cd/m² with a relative lens aperture of 1:1,4. This takes into account the film's photosensitivity in the range from 16 to 2000 GOST units (from 13 to 34 DIN units).

The power source for the exposure metering device is a 6 V element (overall dimensions: diameter 13mm, height 25mm). Control of the power source is ensured automatically. The camera is equipped with synchronizing devices for working with flash lamps.

The camera has a self-timer mechanism. The preliminary work time before releasing the shutter is 7–15 s at all shutter speeds.

The back of the camera is hinged and can be removed from the camera if necessary.

The camera is supplied with a removable eyecup, the design of which allows the use of a diopter lens.

From the editor

As the Kiev-17, but with TTL open-aperture 2-cell CdS exposure metering and LED indicators in the viewfinder. The camera was compatible with Nikon AI (automatic maximum Aperture Indexing) system for coupling the lens to the camera's exposure system.

The camera was produced by the Arsenal Plant (USSR) from 1983 to 1986. Unfortunately, the camera was expensive, and the shutter was unreliable and often malfunctioned, so the camera quickly disappointed the users and, despite all its advantages, was not popular. Production was discontinued for economic reasons in favor of the simplified and cheap Kiev-19.
