For accurate manual focusing of subjects at
infinity, look through the viewfinder or look at
the magnified image on the LCD screen while
turning the focusing ring.

The depth-of-field scale is only valid when the
lens is not tilted or shifted.

The depth-of-field scale is an approximate
indicator.
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.
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 numbers on the scale are aperture settings.
