Benefits of using Lens Hood

The use of lens hood is not simply anti-blur, dust-proof, shock-proof. The main purpose of a Lens Hood is to keep the (unwanted) light rays from straying into the lens causing the image to fail.

You are not required to use a lens hood. But there are several reasons why you should use it. So what's the use of a lens hood?

The first use of a lens hood is to prevent light from the two sides from reaching the outermost lens. If you do not prevent the light from these sources, the image will be flare and reduce the contrast. When using a lens hood, the image gives richer color and has a deeper depth (saturation).

A second use of a lens hood is to protect the lens, prevent hand marks, and avoid collisions that can cause lens breakage. With the lens hood attached, the impact on the lens from the front will be limited, and the impact force will be reduced. However, for ultra-wide angle lenses, the lens hood is usually short and the protection effect is also lower.

For long focal length lenses, the lens hood also prevents rain and dust from clinging to the front lenses, keeping the lens clean and dry. However, if the lens does not have a weather sealed design, the lens should not be wet.

Lens hoods are expensive and not very convenient. Yes, but lenses are more expensive. This is the same as when you choose a D-SLR because you want a high quality image, not a convenient and inexpensive issue.
