Lens design
The thread in the front
part of the lens serves for screwing in the lens hood and attachments. The
distance scale serves for approximate focusing; the distance values are shown
in metres and in foot. The focusing is performed by rotation the ring. Accurate
focusing is performed over the ground glass. The ring serves for fixing the
lens on the tripod.
Operating procedure

Owning to the great mass of the lens it is recommended to use a tripod. The
using of the tripod makes it possible to turn the frame on 90°; in this case
the lens with the camera and the turning ring remains immovable.
The lens focusing is performed by rotation the focusing ring until the sharpest
possible image of the object is obtained on the ground glass.
The delivery set includes three light filters:
UV-1.4x - is a colourless one used to weaken the influence of ultraviolet
rays. In mountainous regions and on water it makes it possible to cut out
the ultraviolet rays. It used at black-and-white and colour photography.
O-4x - is an orange one ensures the obtaining of a contrast image
(black-and-white photography), weakes the influence of atmospheric haze.

Lens care
Photographic lens is a
complicated and sensitive optical instrument that needs careful treatment. Disassembling
of the lens for repairs is admitted only in the special repair shop. The lens
is designed for photographing at the temperature from -15°C to +45°C. when
bringing the lens from the cold into a warm room, don't open its case to
prevent fogging of optical details. Allow the lens to warm up in the closed
case during 3 hours. When not using the lens close its lids. Keep the lens in
its case. Protect the lens from blows, moisture, dirtying and sharp fluctuation
of temperature. Take care of the coated surface of the lens; mousture that is
found for a long time of the coated surfaces may spoil the coating film. Don't
touch the optical details. Remove dust from surface with a clean soft degreased
hair brush. Dirty spots are best removed with a cotton wool wad on a small
wooden stick. It is necessary to slightly moisten a wad in rectified alcohol,
ether or mixture of these substanses. The large dirtying remove with several
wads. Clean the surface with circular motions, gradually moving from the center
of the lens to its edges.
