The aperture ring regulates the amount of light transmitted to the
film plane. The amount of light transmission is halved when the
aperture is changed to the next larger f value (for example, when
f/4 is changed to f/5.6), and doubted when it is changed to the
nexl smaller f value. The aperture also controls the depth of field,
a lens property giving you varying depth in the plane of focus at
different apertures. (Refer to page 100) To set the aperture, turn
the aperture ring until the desired aperture setting is aligned with
the aperture/distance scale index. The aperture ring can be used
at in-between positions. With the exception of the Mirotar lenses,
all Zeiss lenses feature automatic diaphragms that stop down to
the selected aperture when the shutter is opened upon activatron
of the shutter release. Thus, your viewfinder always gives you a
brilliant image at full aperture of the lens in use.
