[. . . ] These differ from the 4 mainly in having a wider rangefinder base for improved focusing accuracy, shutter speeds of 1/30th to 1/500th only, seperate pc connectors for M and X synch, hinged back, and oh happy inspiration, a top mounted rewind knob big enough to be easily gripped by human fingers! 1 2 3 4 5 6 7 Self Timer Timer Release Button PC connection Winder Knob Film Counter Rewind Ring Shutter Release 8 9 10 11 12 13 Shutter Speed Selector Rangefinder Optic Flash / accessory shoe Viewfinder Rewind Knob Diopter Lever 1 2 3 Winder Knob Rewind Ring Shutter Release 4 5 6 Shutter Speed Selector Accessory Shoe Rewind Knob LOADING/UNLOADING FILM Note that this rendering is of a Fed 3. The latching mechanism and its operation are identical. To access the film compartment you remove the one-piece back. It is secured by two rotating latches on the bottom plate. [. . . ] This is because the 1/30th setting works differently than any other, timing the full opening of the shutter to coincide with the maximum light output from flash. To change speeds FIRST COCK THE SHUTTER (wind the film). Now grasp the speed selector knob and gently pull up while rotating the black marker to the desired speed on the surrounding dial. You will notice that the knob moves easily from 1/30th counterclockwise until it reaches the 1/15th mark. At that point resistance will be felt, and a noise like the winding of a clock will be heard. This is normal as the slow speed mechanism is engaged. The speed selector cannot be moved counterclockwise farther than the 1 second mark. To go from on second to 1/30th you must turn the knob clockwise all the way around past B. USING THE VIEWFINDER/RANGEFINDER Note the lever under the rewind knob at the far right (viewed from the back) of Zorki 4. This is a diopter correction, allowing you to adjust the viewer for your own eyesight. In most cases, this will eliminated the need for glasses while using your Zorki 4 - a good thing as the hard plastic eyepiece may scratch your eyeglasses. To adjust the diopter push the lever left or right until the viewfinder is at its maximum clarity. Make certain not to have your hand in front of the viewfinder as you will see only through the rangefinder optic. I cannot find a single setting that works for all focusing distances, but it is quick and easy to adjust at any time. Now note the bright "spot" in the middle of the viewfinder. It will provide a spit image of the object in your viewfinder. Rotate the focus ring left or right until the split image merges into a single image. If this cannot be accomplished, you are too close to the object for that particular lens. What you see in the viewfinder is almost certainly not what the film "sees. " At normal distances, and with the "normal" 50mm lens, there is little difference. Change to a wide angle or telephoto lens, or try and move in close and other factors come into play. The Zorki 4 viewfinder has a field of view roughly comparable (at least to my eyes) of a 50mm lens. This will depend to a certain extent on the amount of your diopter correction. [. . . ] CAUTION: KMZ (Zenit, or sometimes Zenith), made some LTM mount lenses for their early SLR cameras and these have a different focal plane depth. They may mount, but will not operate properly and could damage your camera. Caution: Not all LTM mount lenses will work with your Zorki 4. Some lenses use a "tongue" to push against the rangefinder cam, rather than a cylinder. [. . . ]
