also be used on other lenses of the same focal 
length and with similar mounts. After screwing 
it into place, rotate the Stereo Attachment or 
its inner section until the dividing line running 
through the middle of the ground-glass screen 
is exactly vertical, i.e. parallel to the longer sides 
of the two half-images,which should already 
be visible on the focusing screen. This vertical 
adjustment can be simplified by checking that 
a selected point in each of the two half-images 
is at an identical distance from the lower edge 
of the image frame. The large Stereo Attach-
ment can then be locked by turning the knurled 
locking ring in the opposite direction. Focusing 
is performed by means of the reflex image 
in the usual manner. When using the Stereo 
Attachment the normal exposure should be in- 
creased by 1.5 times; since the two half-images 
must always be side-by-side, the EXA IIa should 
always be held in the horizontal position; it is 
not possible to make upright stereo pictures.

We will gladly send you any special leaflets free 
of charge; please write to let us know the type 
of work you are interested in.

We would also refer you to the following text- 
book:

“Foto-Exkursionen mit der EXA” by Werner Wurst 
(Fotokino Verlag Halle, Halle/Saale).

There may be certain slight differences between 
the appearance of the camera and its equip-
ment, and the illustrations in this booklet.
