Is a lens hood necessary?

SLR camera hood is necessary.

Camera lenses all have an accessory called a "lens hood," which looks like a short, circular lens barrel that is fixed to the front of the lens. The main reason why a lens hood is an essential photography accessory is that it makes your photos look more transparent. Its purpose is to prevent photos from fading easily under certain lighting conditions.

This is because harsh, bright light enters the camera lens and is spread over part of the image. A lens hood can alleviate such problems by acting as a cap over the front glass element. After attaching the lens hood, the contrast and sharpness of the lens are greatly improved, and the lens hood is especially useful when shooting in the sun.

Advantages and disadvantages of lens hoods:

1. Advantages

In addition to protecting photos from strong light, lens hoods can also protect photos from physical collisions. on, greatly protecting the camera. This is because the lens hood will absorb the brunt of most impacts while it is worn over the lens. If the lens hood is damaged, it is much cheaper than replacing the lens directly.

2. Disadvantages

Some lenses, especially wide-angle lenses and when using flash, may darken the four corners of the photo when the lens hood is installed. In addition, adding a lens hood will also increase the overall length, which may cause inconvenience. This is especially obvious with telephoto lenses. If the lens is long, the capacity of the backpack and the shooting space must be considered, so be careful not to bump the lens.
