The lens
Focus range
The built-in lens provides an optimal image sharpness for objects
between 1 metre and infinity (depth of field).
Cable
A 4-wire system cable (see specifications) is supplied standardly.
For an optimum picture and sound quality a dual 'twisted-pair' cable
should be used.

Do not touch the glass of the lens. This could damage the
delicate coating on its surface. If the lens has to be
cleaned, use a special lens cleaning tissue, available at any
good camera store.
