Features:
\ 1. It can prevent the entry of non-imaging light and avoid fog when shooting in backlight, side light or flash photography.
\ 2. It can avoid the surrounding scattered light from entering the lens when shooting with forward light and side light.
\ 3. In lighting photography or night photography, it can prevent the surrounding interference light from entering the lens.
\ 4. It can prevent accidental damage to the lens, and it can also prevent fingers from accidentally touching the surface of the lens. It can also shield the lens from wind, sand, rain and snow to some extent.

DC-s (screw structure): When using, screw the petal-shaped lens hood directly on the lens, and align the two high petals of the lens hood with the upper and lower positions of the lens, turn the nut clockwise and lock it. This is the simplest and most reliable connection structure in the world.

\friendly reminder:
\ \ Strictly speaking, the hood is an integral part of the lens optical system. A lens is composed of several or more than ten lenses. And every lens has two reflective surfaces, and a lens has dozens of reflective surfaces!
\ The more reflective surfaces, the greater the impact on the lens imaging! Especially when shooting in backlight or side backlight, multiple reflective surfaces will interfere with each other to form a halo. Halo makes the picture dim(Color desaturation )Or flares appear.
\ Sometimes the shots seem to be misted with a layer of mist. In fact, this is caused by the unused lens hood, rather than the quality of the lens! The inner wall of the high-quality hood is processed with multiple matting. The reflectivity of the inner wall
\ It is only about 10%, and it will not refract the lens during use. The use of a lens hood is useful for suppressing image halo, avoiding stray light from entering the lens, blocking rain and snow from splashing, protecting the camera and lens from accidental collisions, and is useful for giving full play to
\ The potential quality of the lens optics will play a good role and effect.
\ When shooting outdoors, you should use the hood as much as possible, which is very beneficial for improving the quality of shooting. Under the same test conditions(Side backlight, distant view)Do a set of experiments. For both the use of the hood and the non-use of the hood
\ Group to shoot. Among them, the picture quality of a group of pictures using the hood is much higher than that of a group of pictures not using the hood! The performance is: the halo of the sky in the upper right corner of a group of pictures using the hood disappears, and the picture color
\ Saturation and clarity have been significantly improved.
\
\ Hope it helps you. Personal advice, put on the hood.
