Infinity compensation mark

Distance index

To compensate for shifting of the infinity focus point that results from changes in temperature. The infinity position at normal temperature is the point at which the vertical line of the L mark is aligned with the distance indicator on the distance scale.

For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.

The dedicated Lens Hood ET-155 helps to prevent stray light from entering the lens and protects the front of the lens from rain, snow or dust.

To attach the hood, loosen the hood locking knob by turning it counterclockwise. Fit the hood onto the lens hood mount, and tighten the locking knob to fix it in place. Use the same procedure, in reverse, to remove the hood.
