Setting the Lens Aperture
The lens aperture adjusts the light volume that reaches the film
and also the depth-of-field (see page 31).
The required "F" stop can be obtained by turning the lens aperture
ring until the figures align with the index mark.
The following table shows the relation between aperture value
and exposure time.
