11. Fitting the Lens Cap
Reverse the lens hood, slip it over the lens, and tighten the lock knob to fix it in place.
Lift the hook and loop fastener, and fit the cap so that the lock knob rides up the slot in the cap.
With the lock knob at the opening in the cap, close the fastener to fix the cap in place as shown.
