Ratchet Steps and Magnification Levels | Leica M205 FA instruction

Ratchet Steps and Magnification Levels

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 147 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.
