Strictly speaking, the light shield,lens hoodIt is a component of the lens optical system. A lens is composed of several or dozens of lenses. And each lens has two reflective surfaces, with each lens having dozens of reflective surfaces! The more reflective surfaces there are, the greater the impact on lens imaging! Especially in backlit or side backlit shooting, multiple reflective surfaces will interfere with each other to form a halo. Halo can cause the color of the image to become dull (color saturation) or flare up. Sometimes the captured image seems to be covered in a thin mist, which is actually caused by not using a light shield, rather than a quality issue with the lens!
The inner wall of the light shield is subjected to multiple extinction treatments. The reflectivity of its inner wall is only about 10%, and it does not refract the lens itself during use. The use of a light shield can effectively suppress image halo, prevent stray light from entering the lens, block rain and snow splashes, protect the camera and lens from accidental collisions, and fully utilize the potential optical properties of the lens.
When taking outdoor photos, it is advisable to use a light shield as much as possible, which is very beneficial for improving the quality of the shot. A set of experiments was conducted under the same testing conditions (backlit and distant). Take photos of two groups with and without a light shield. Among them, the group of images using a light shield showed a significant improvement in image quality compared to the group of images without a light shield! Manifesting as: The halo in the sky area in the upper right corner of a set of images using a light shield disappears, and the color saturation and clarity of the image are significantly improved.
