Focusing the lens

Focusing is accomplished while viewing the subject
through the viewfinder of your camera and rotating
the focusing ring. Since the aperture is preset, you
will find under certain light conditions a shadow
appearance on the split-image section of your focu-
sing screen. In this case, simply focus on the edges
of your subject with the outer center of your prism.
 NOTE: In order to compensate focusing when nor-
mal focusing position may differ due to extreme tem-
perature change, the focusing ring has been designed
to allow rotation beyond tilefixed engraved marks
of the distance scale. To avoid error, focusing should
always be made while looking through the view-fin-
der.
