A camera lens hood is an essential accessory for any photographer. It is a cone- or barrel-shaped piece of plastic, metal, or other material that attaches to the front of a camera lens.
The primary purpose of a lens hood is to block out unwanted light that can cause lens flare and ghosting, which can negatively impact the quality of your photos.
In addition to improving image quality, lens hoods also offer physical protection for the front element of your lens, making them an important tool for preserving the longevity of your equipment.
In this blog post, we will delve into the different types of lens hoods, how to choose the right one, and the benefits of using a lens hood in your photography.
If you are interested in camera gear then here are some posts on different types of camera gear that can improve your photography.
Camera lens hood purpose
A camera lens hood is a device that is attached to the front of a camera lens and is used to block out unwanted light. Here are some main purposes a lens hood servs.
Reduce lens flare
The purpose of a camera lens hood is to reduce lens flare, which is a common problem that occurs when light reflects off the surface of the lens and creates a wash of glare across the photograph. This can be particularly problematic when shooting in bright light or when the sun is in the frame.
Lens hoods work by extending the length of the lens and shading the front element from the sun or other bright light sources. This helps to reduce lens flare and improves the overall contrast and color saturation of the photograph.
Lens protection
In addition to reducing lens flare, lens hoods can also help to protect the front element of the lens from accidental bumps and scratches.
Block stray light
Another benefit of using a lens hood is that it can help to improve the overall image quality by reducing the amount of stray light that enters the lens. This can be especially useful when shooting in challenging lighting conditions, such as backlit scenes or when shooting into the sun.
Overall, the purpose of a camera lens hood is to improve the quality and clarity of the photographs that you take by reducing lens flare and stray light, and by protecting the front element of the lens from damage.
Camera lens hood types
There are several different types of lens hoods that are designed to fit different types of lenses and to provide different levels of shading. Some common types of lens hoods include:
- Tulip-shaped hoods: These lens hoods have a flared shape that is wider at the front and narrower at the back. They are often used on wide-angle lenses and are designed to shade the corners of the frame.
- Round hoods: These lens hoods are circular in shape and are typically used on standard or telephoto lenses. They are designed to shade the entire front element of the lens.
- Rectangular hoods: These lens hoods are rectangular in shape and are often used on prime lenses or on lenses with long focal lengths. They are designed to shade the entire front element of the lens and to provide extra protection from side light.
- Collapsible hoods: These lens hoods can be extended and collapsed as needed, making them convenient for storing and carrying. They are available in a variety of shapes and sizes to fit different types of lenses.
- Screw-in hoods: These lens hoods are threaded and can be screwed onto the front of the lens. They are available in a variety of shapes and sizes to fit different types of lenses.
- Petal-shaped hoods: These lens hoods have a petal-like shape that is wider at the front and narrower at the back. They are often used on wide-angle lenses and are designed to shade the corners of the frame.
In addition to these types of lens hoods, there are also hoods available that are specifically designed for use with filters, such as polarizing filters or neutral density filters. These hoods are typically rectangular or square in shape and are designed to fit over the front of the filter.
Can you put a lens hood on any lens?
Yes, you can put a lens hood on any lens. However, it is important to use the correct size and shape of lens hood for your specific lens in order to get the best results.
Using the wrong size or shape of lens hood can result in vignetting (dark corners) in your images or may not provide sufficient shading to effectively reduce lens flare.
To find the correct size and shape of lens hood for your lens, you can refer to the manufacturer’s specifications or consult a lens hood chart. These charts typically list the recommended lens hoods for each type of lens based on the focal length and aperture.
It is also important to note that some lenses, such as wide-angle lenses, may require a special type of lens hood that is designed to shade the corners of the frame. In these cases, it is important to use the correct type of lens hood to avoid vignetting.
Overall, it is generally a good idea to use a lens hood whenever possible to help reduce lens flare and improve the overall image quality of your photographs.
Do you need a lens hood if you have a UV filter?
It is generally a good idea to use a lens hood in conjunction with a UV filter, as this can help to provide additional protection for both the filter and the front element of the lens.
A UV filter is a clear filter that is placed over the front of the lens and is designed to block out ultraviolet (UV) light. UV filters are often used to help reduce haze and improve the overall clarity of the photograph, particularly when shooting in bright or high-altitude conditions.
While UV filters can help to reduce lens flare and improve image quality, they do not provide the same level of shading as a lens hood.
A lens hood is designed to block out unwanted light and reduce lens flare by extending the length of the lens and shading the front element from the sun or other bright light sources.
By using a lens hood in conjunction with a UV filter, you can get the benefits of both devices and help to improve the overall image quality of your photographs.
It is important to note, however, that you should use the correct size and shape of lens hood for your specific lens to avoid vignetting (dark corners) in your images.
Can you use a lens hood indoors?
It is generally not necessary to use a lens hood when shooting indoors, as lens flare is typically not a problem in these situations. Lens flare is most commonly caused by bright light sources that are in the frame or that are shining directly onto the lens.
This is less likely to be a problem when shooting indoors, as the lighting is typically more controlled and the sources of light are typically not as bright as the sun.
However, there may be some situations where you may want to use a lens hood when shooting indoors. For example, if you are shooting in a brightly lit room with large windows or other sources of bright light, a lens hood may help to reduce lens flare and improve the overall image quality.
Additionally, if you are using a lens with a particularly large front element, you may want to use a lens hood to protect the lens from accidental bumps and scratches.
Overall, while it is not generally necessary to use a lens hood when shooting indoors, there may be some situations where it can be useful.
It is always a good idea to assess the lighting conditions and the specific needs of your lens before deciding whether or not to use a lens hood.
5 Tips on selecting the right lens hood
