Uv Shortpass Filter: Why Do You Need A Uv Filter For Your Lens?

Published on

The UV shortpass filter is an important tool for photographers. It lets UV light pass through but blocks longer wavelengths. It improves clarity, color saturation, and reduces lens flare. It also protects the lens from dust, moisture, and scratches. This filter is easy to clean and useful for achieving high-quality photos. Photographers can capture better images and keep their lenses safe by using this filter.

What is a Shortpass Filter?

A shortpass filter refers to an optical device that permits the transmission of shorter wavelengths of light while impeding or reducing longer wavelengths. In simpler terms, it allows ultraviolet (UV) light to pass through while hindering other types of light.

What Type of Filter is UV?

UV, in this context, represents a specific type of filter. UV filters are categorized as shortpass filters since they facilitate the transmission of UV light while impeding visible and infrared light.

What is a UV Filter Used For?

UV filters serve multiple purposes and offer several benefits. Let’s explore some of the key uses of UV filters:

  1. Eliminating UV Haze: 

UV light tends to create a hazy effect in photographs, especially in landscapes or high-altitude settings. By employing a UV filter, you can counteract this haze and capture clearer and crisper images.

  1. Protection against Physical Damage: 

Acting as a barrier, a UV filter shields the front element of your lens from potential harm caused by dust, moisture, and accidental scratches. This way, the filter acts as a sacrificial layer, preserving the lens’s integrity.

  1. Enhancing Color Saturation: 

UV filters aid in boosting color saturation, particularly in outdoor photography. By filtering out unwanted UV light, these filters help bring out richer and more vibrant colors, resulting in captivating images.

  1. Minimizing Lens Flare: 

Unwanted lens flare can occur when strong sources of light hit the lens at certain angles. A UV filter can effectively reduce lens flare, resulting in cleaner and more professional-looking photographs.

Why Do You Need a UV Filter for Your Lens?

Now that we’ve touched on the advantages of UV filters, let’s delve into the reasons why you should consider incorporating one into your photographic gear:

Protection of Valuable Lenses: 

Lenses can be expensive investments, and any damage to them can be financially burdensome. By attaching a UV filter to your lens, you create an additional layer of defense against potential harm, ensuring the longevity of your valuable equipment.

Convenience and Ease of Cleaning: 

It is far simpler to clean a UV filter than it is to clean the front element of your lens. Dust, smudges, and fingerprints can be easily wiped away from the filter’s surface, safeguarding the lens itself.


UV filters can be left on your lens at all times, as they have no significant impact on the exposure or quality of your images. This means you can readily switch between different filters without compromising the integrity of your shots.

What is the Difference Between UV and CPL Filters?

While both UV and CPL filters are popular among photographers, they serve distinct purposes. Let’s examine the differences between these two types of filters:

  1. Purpose: 

UV filters primarily address the issues of UV light and its effects on image quality, while CPL filters (Circular Polarizing filters) are specifically designed to reduce glare, enhance color saturation, and manage reflections.

  1.  Light Transmission: 

UV filters allow UV light to pass through while blocking other types of light, whereas CPL filters selectively filter out polarized light in certain orientations.

  1. Effect on Exposure: 

UV filters have minimal impact on exposure, making them suitable for everyday use. On the other hand, CPL filters reduce the amount of light reaching the camera’s sensor, resulting in a slight darkening of the image and potentially requiring adjustments to the camera’s exposure settings.

  1. Application: 

UV filters are commonly used as a protective measure and to improve overall image clarity. They are suitable for a wide range of photography genres, including landscapes, portraits, and general outdoor shooting. CPL filters, on the other hand, are particularly effective in situations where reflections need to be managed, such as photographing bodies of water or glass surfaces.


Do UV filters affect image quality?

UV filters, when of high quality, have negligible impact on image quality. However, it’s crucial to invest in reputable brands to ensure optimal clarity and prevent potential issues like reduced contrast or lens flare.

Can UV filters completely eliminate UV light?

While UV filters significantly reduce UV light, it is important to note that they cannot entirely eliminate it. Nonetheless, they effectively minimize the adverse effects of UV radiation on your photographs.

Can UV filters replace lens caps?

While UV filters provide some level of protection, they cannot completely replace lens caps. Lens caps offer comprehensive coverage and safeguard against dust and other debris that might enter through the sides of the filter.

Are all UV filters the same?

UV filters vary in terms of quality and effectiveness. It is advisable to choose filters made of high-quality materials, such as multi-coated glass, to ensure optimal results and avoid any potential degradation of image quality.

Can I stack UV filters with other filters?

Stacking filters can sometimes lead to issues like vignetting or decreased image quality. If you need to use multiple filters simultaneously, consider investing in thin-profile filters specifically designed for such situations to minimize potential drawbacks.

Final Thought

UV shortpass filters are important for clear photos. They let UV light through but block other wavelengths. This improves image quality, protects lenses, and enhances colors. UV filters are different from CPL filters and serve unique purposes. Knowing the differences helps you choose the right filter for different shooting situations. Investing in good filters gives the best results and protects your lenses. Add a UV filter to your photography gear for better images.
