26 08 Lens characteristics entry (at a time of lens replacement)
Because each lens has a variance in focal distance, the lens moving distance in any zoom mode must
correspond with the focal distance of the lens. The zoom ratio varies proportionate to the variance of
the lens focal distance.
To avoid focus problem, the class of the lens focal distance (refer to chart on page 7-11) is stored in the
memory using the test command. In a variable zoom mode, the lens moving distance that corresponds
to the lens focal distance is obtained on the basis of the data so as to produce the accurate zoom copy.
