WHAT IS THE PURPOSE OF A LENS HOOD?
The lens hood is a piece of plastic that clips onto the front of a camera lens and extends beyond it.
Lens hoods serve two primary purposes:reducing lens flare, and protecting the lens from damage.
The intended purpose of the lens hood is simply to reduce lens flare, but the protection it provides to the glass elements of the lens is a beneficial side-effect.

SHOULD I USE A LENS HOOD ON MY CAMERA?
The short answer is yes.
While shooting without a lens hood can still produce great pictures most of the time.
if any light happens to bounce into the lens from the sides, the contrast and color in the image is significantly reduced.
Also, it is nice to have a lens hood for protection of the lens.
