Figure 1-4 shows the components within the viewfinder which direct the image
from the front window to the eyepiece. There are six plastic lenses, four mirrors, a
mask and a black border which define the image and clearly show the extent of the
image which will be captured on the film frame, and a plastic wedge which aligns
the image relative to the eyepiece.
