The camera lens picks up the intermediate image formed by
the zoom lens and relays this image to the fi

There will be no difference in magnification between the
visible mode and the photographic mode. T e entire film
format will always be filled regardless of the magnification.
One point should be made clear and that is that the observer
will actually see more of the object through he eyepiece than
he can photograph. This is because the virtual image formed
by the eyepiece has a larger diagonal than that of the film
pack.
The camera lens will be a short focal length
the angular coverage and aperture are both
be no difficulty in achieving a diffraction lirr.

The circle represents the image or picture as seen through the lOX eyepiece
at any magnification. The rectangle represents the size of the polaroid. The
polaroid format can' handle only 33.9% of the visible image, in other words
33. 9% of the total area of the object will appear on the 3" x 4" polaroid picture
regardless of the size of the object , but at the same magnification as seen
through the eyepiece.
