The zoom button can optionally be operated
either with or without ratchet steps. Continu-
ous zoom is possible when the ratchet steps are
disabled, which many users find convenient.
On the other hand, when the ratchet steps are
enabled, photographs, measurement results
etc. can be reproduced more accurately.
Enabling and disabling ratchet steps
1. Push the top button downwards to disable
the ratchet steps.
2. Push the bottom button upwards to enable
the ratchet steps.
Magnifications and fields of view
The formula on page 157 provides additional
information about the magnifications and field
of view diameters, with consideration given to
the position of the magnification changer and
the eyepiece and objective combination used.
