7. Infinity Compensation Mark

To compensate for shifts in the lens’ infinity position on the distance scale due to temperature changes, the focusing ring can be turned slightly beyond the normal infinity position. In room temperature, the infinity position on the distance scale is indicated by the L symbol which should be aligned with the distance scale index.

To confirm accurate focus, look through the viewfinder.
