3. Infinity Compensation Mark
Infinity compensation mark
Distance scale
To compensate for shifting of the infinity focus
point that results from changes in temperature,
there is a margin at the infinity (∞) position.
The infinity position at normal temperature is the
point at which the vertical line of the distance
scale L mark is aligned with the distance index.
For accurate manual focusing of subjects at infinity,
look through the viewfinder or look at the magnified
image* on the LCD screen while rotating the
focusing ring.
* For cameras with Live View shooting capability.

The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale.
The number on the scale is the aperture.
The depth-of-field scale is an approximate indicator.
