10. Hood
The special hoods that come with all these
lenses cut out unwanted light and protect the
front of the lens from rain, snow, and dust.
To attach the hood, loosen the hood lock knob
by turning it counterclockwise. Fit the hood onto
the lens’s hood mount, and tighten the lock knob
to fix it in place. Use the same procedure, in
reverse, to remove the hood.
9. Infinity Compensation
Mark

the focusing ring.
To compensate for shifting of the infinity focus
point that results from changes in temperature.
