Infinity Compensation Mark
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
mark is aligned with the distance index.

- For accurate focusing in MF on subjects at infinity distance, look through the viewfinder or at an enlarged image on the LCD monitor* while turning the focusing ring.
