82mm rubber three-purpose lens hood(Wide angle, medium focal length, telephoto)
1. In the backlight, side light or flash photography, it can prevent the entry of non-imaging light and avoid fog.
2. It can prevent the scattered light from entering the lens when taking photos 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.
There are many sizes of hoods, and the one that matches the focal length of the lens should be selected. The shorter the focal length of the lens, the larger the angle of view and the shorter the hood. If the hood of a standard lens is used on a wide-angle lens, it will inevitably produce the consequence that the image around the screen cannot be imaged. On the contrary, it cannot play the role of shading. When using a zoom lens, it is best to use a retractable lens hood that can be used for your own use.
Lens hoods are widely used in backlight photography, generally speaking, to avoid glare. However, if the light source is close, glare may still occur. At this time, you can use your hand to block the hood on the side where the light source is located. Whether the glare is eliminated, you must observe it clearly in the viewfinder.
