Basically binoculars are made up of the objective lenses for long

focal points, and the eyepiece lens, for short focal points.

The light from each to the two objective lenses which forms the

image of an object (Fig 4-a), passes through the barrel and hits

the eyepiece lens, which enlarges the image (Fig 4-b).

Create a telescope using two camera lenses

Attach a wide-angle lens to a telephoto lens. Without

shifting the optical axis, look through from the back of

the lens and adjust the distance between the two lenses.

You will eventually see a sharp inverted image.

This is the basic structure of a telescope. Put two of these side

by side and you have a pair of binoculars. In addition, the

longer the focal point of the telephoto lens and the shorter the

focal point of the wide-angle lens, the more the image will be

magnified. It is also possible to achieve focus by adjusting the

distance between the two lenses. It' s very simple.

Tested with the EF 300 mm f/4L and EF 24 mm f/2.8,

(Fig. 4)

the outcome was pretty obvious.
