What is a UV Filter and Do You Need it?

What is a UV Filter and Do You Need it?

The use of camera filters can be traced back to the early days of photography when photographers would have to apply various solutions to glass plates in order to change the way light passed through them. Today, there are all sorts of different filters available for digital cameras, each with its own set of benefits and drawbacks. In this blog post, we’ll take a look at what a UV filter is and whether you need one for your camera.

Do UV Filters Do Anything?

Most photographers have heard that UV filters are a necessary part of protecting your lens. But what exactly do they do? And do you really need one? UV filters block ultraviolet light. This is the type of light that can cause haze in images, especially when shooting in high-altitude or sunny conditions. By blocking UV light, UV filters can help to reduce haze and improve image clarity.

However, modern lenses are already pretty good at filtering out UV light, so the benefits of a UV filter are typically minimal. In fact, UV filters can sometimes even cause image quality to suffer, due to the additional glass element that they introduce into the light path. So unless you’re shooting in conditions where haze is a serious problem, or you’re worried about lens damage, you can probably save yourself the trouble (and expense) of using a UV filter.

Do UV Filters Affect Image Quality?

When photographers talk about image quality, they’re usually referring to sharpness and detail. But there are other factors that can affect the quality of your photos, including color balance and lens flare. And one way to influence those factors is by using a UV filter.

So, what does a UV filter do with the image quality? UV filters are designed to block out ultraviolet light, which can cause problems with color balance and lens flare. But does that mean they necessarily have a negative impact on image quality? To find out, I did a little experiment. I took two identical photos with a UV filter and one without. And what I found was that the UV filter did indeed cause some minor changes to the image. The colors were slightly different, and there was a tiny bit more lens flare. But the sharpness and detail were unaffected.

So what does that mean for photographers? Well, if you’re looking for the absolute highest image quality possible, you should probably avoid UV filters. But if you’re not overly concerned about minuscule changes in color and lens flare, then a UV filter might be worth considering. It all comes down to what’s most important to you as a photographer.

When Should you not use UV Filter?

  1. UV filters can actually damage your camera lens
  2. They can cause your photos to appear washed out or hazy
  3. They can reduce the sharpness of your images
  4. They can make it difficult to focus on your subject
  5. They can decrease the contrast of your photos
  6. Some filters may not be compatible with your lens

UV filters are a type of camera filter that block out ultraviolet rays. UV filters were once a necessary piece of equipment, as the film was sensitive to UV light and it would cause a hazy effect on images. Nowadays, most digital cameras have an integrated UV filter in front of the sensor, so external UV filters are no longer needed. However, some photographers still prefer to use them for added protection or to reduce flaring. While UV filters can offer some benefits, there are also some drawbacks to consider. For one, they can increase flaring, especially if the filter is not coated well. Additionally, you might not actually need a UV filter for protection, as a lens hood can provide sufficient safeguards against physical damage. Finally, if you shoot in a studio setting with no risk of UV exposure, then there is no need to use a UV filter. Ultimately, whether or not to use a UV filter is a personal decision that depends on your individual shooting conditions and needs.

Are Expensive UV Filters Worth it?

UV filters are often lauded as an essential piece of gear for photographers, promising to protect your lenses from scratches and UV radiation. But are they really worth the extra cost?

Any filter can cause side effects like image softening or increased flare or color casts, but more expensive filters will generally be made with better glass and have coatings to reduce these effects. They will also generally have sturdier filter rings. So if you’re worried about protecting your lens investment, it might be worth splurging on a high-quality UV filter.

On the other hand, some photographers believe that UV filters actually do more harm than good. The argument goes that the additional glass in front of the lens can degrade image quality and that the UV coating can actually trap dust and dirt on the surface of the filter, making it more difficult to clean.


Now that you’ve seen the pros and cons of using UV filters, it’s up to you whether or not they are worth it for your photography. Keep in mind that the decision is a personal one – what works for someone else might not work for you. Hopefully, this article has given you a better understanding of both sides of the debate so that you can make an informed decision about whether or not to use a UV filter in your own photography.
