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.

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 and for turning the frame on 90° during the arrangement of the subject.
