3. INSTRUCTIONS FOR USE
Install and remove the lens according to the rules laid down in the Operation Manual of the cameras. Set the required
diaphragm by turning ring 4. The diaphragm shuts to the selected value automatically when the release button of the
camera is depressed. The image sharpness is obtained by turning ring 1 with a distance scale 2.
The field depth can be determined by means of scale 3 on the distance scale 2 depending on the distance to the
focused object and the selected diaphragm value.
4. USE OF LIGHT FILTERS
The lens cannot be used without light filter! It comes with UV filter already installed on the rear side of lens.
The light filter YG-1.4
Х, yellow-green and light, improves the tone reproduction of multicolor objects on high-sensitive
photo materials with a slight loss of their sensitivity. With medium-sensitive photo materials, the practically correct tone
reproduction of multicolor objects is attained.
The light filter B-1.4
Х, blue, requires a slight enlargement of exposure and is the most suitable for taking pictures with
filament lamps as it provides for the correct tone reproduction of color objects especially in taking pictures with the use of
high-sensitive photo materials.
When shooting outdoors (in the day lighting) the blue light filter singles out a haze, improves the image of shades in a
sunny day, provides for the more correct reproduction of space.
The light filter O-2.8X, orange, fully absorbs Ultraviolet Rays. It is used to obtain a particular contrast in shooting the
compositions with clouds, water surfaces, landscapes with a noticeable shading of verdure, etc.
5. CARE AND STORAGE
The lens is a complicated optical device and should be handled and kept with great care. Protect the lens against

mixture.
