The Exposure.
Before taking a picture, make sure that the
lens is clean; if necessary, it is cleaned
with a soft linen cloth.
Slightly tilted downwards, the camera
automatically opens into the ready position
when you press button 4 (Fig. 8). No
further distance setting is necessary. The
camera produces sharp images from a
distance of 2.5 meters to ∞ (the symbol
character means infinitely far away). With
the help of a separately purchasable
attachment lens, which is attached to the
front of the lens, sharp close-ups can be
achieved from a distance of 1 to 2.5
meters. (Most favorable distance for
maximum sharpness is 1.6 to 1.9 m.)
