Metal Lens Hood

Lens hoods guard against uncontrolled, stray light and unwanted reflections which result in reduced contrast and possible "ghost Images". In general, the use of a lens hood is recommended because better contrast improves the appearance of the photograph. This accessory also offers protection for the front lens element against rain and mechanical damage.
