Precautions on Shutter Operations (cont.) 30

250mm f/6.3 and 80mm f/3.7 lenses.

Shutters of these lenses have no self-cocking system, requiring the shutter to be set manually after each film advance.

For certain lens-shutter assemblies (such as the formar 80mm f/3.7 lens), the release lever of the lens-shutter can be depressed many times even though the shutter is not cocked. When the shutter is not cocked, the shutter blades do not open.

When using this type of lens- shutter, no picture will be recorded on the film if the shutter button is depressed without cocking the shutter. If you find the shutter blades are unopened after depressing the shutter button, the shutter button cannot be depressed again by the double exposure prevention device even if the shutter is cocked afterwards. In this case, set the multiple exposure dial to the 'MULTI' and depress the shutter button, or release the shutter by pushing the release lever on the lens-shutter assembly.
