Every lens purchase includes a UV filter.You may have heard about UV lens filters preventing scratches. I agree with you, but do you know how to select the best protection lens filter for your camera?
A UV Protection Filter (Ultraviolet Filter) is one of the best lens filters for protecting your camera lens. The quality uv protection lens filter protect your expensive lens from physical damage (scratches, bumps) and have little or no effect on the quality of the images.
How Does a UV Filter Work?
Film photography was the first to use ultraviolet filters (Ultraviolet Filters). A UV filter protected the film from unwanted ultraviolet light by blocking it. Without a UV filter, the image suffered from haziness and fogginess, especially in blue hues.
Due to the presence of built-in UV filters on the sensor level of modern digital cameras, UV filters are no longer necessary.
There is a common misconception that UV filters reduce chromatic aberration or color fringing, but I have never observed any evidence to support this claim. Based on my experience, if a lens produces color fringing as a result of poor construction, no filter will be able to correct it. The reduction in chromatic aberration caused by UV filters is not significant enough to affect the quality of an image if the reduction occurs.
In today’s world, UV filters serve only the purpose of protecting. Filters that protect against UV light and those that are clear are very similar.
UV protection lens for modern photography
A UV protection lens filter is an essential part of modern photography
There is no clear consensus in the photography community regarding the use of UV filters for digital photography protection.
Different photographers approach UV protective filters differently.
In accordance with the manner in which UV filters are used. There are three general categories of photographers.
Some photographers never use protection lens filter because they believe that adding an extra layer of glass in front of an expensive, state-of-the-art lens can potentially degrade the quality of the image. We call these photographers “the perfectionists.”
There are two groups.
It is only necessary for photographers in the second group to use UV protective filters when necessary. Typically, your lens’ front element is cleaned.
Around 100 times each day. At the Burning Man festival in the desert, for example. Getting too much sand or dust in your lens can damage it.
There are three groups. As a final group of photographers, there are those who immediately attach a UV protection filter to their lenses upon purchase and do not remove it. The minimal degradation in image quality justifies the risk of damaging the lens in the long run.
Here are some tips on how to use UV protection lens filters
It was not long ago that I was a member of the first group of “perfectionists” who refused to use the protective filter. To prevent any potential physical damage to my lens, I thought using the lens hood was a more effective method of protection.
My frequent travels to the West Coast of the United States changed my mind about the strong winds along the coast, and saltwater mist is always present in the air, even when it is not raining. It is possible to damage the coating on any lens, especially if there is salt residue on the front element, by continuously wiping it.
At this point, I have UV protection filters for all my lenses, but they mostly stay in my bag. I only use them when necessary. As I travel along the coast, I always attach a filter to the front element of my lens. The coating on the lens can get damaged if it’s constantly wiped.
What are the negative effects of using UV protection lens filters?
The disadvantages of using UV protection lens filters using protection lens filter, we need to understand the properties of glass in optics. They are light transmission and light reflection. They indicate the ratio of light that comes through glass versus the light reflected by the glass.
A UV protective lens generally filters out 5% of the light, which means you’ll see more lens flare if you shoot through it. You should use UV protective filters with the highest transmission and the lowest reflection.
A UV protective filter that transmits the most light. That reflects the least should be used in practical terms are of plastic. The reflection rate of plastic is much higher than even regular glass and can be higher than 15%. Stay away from UV protective filters should have the highest transmission and the lowest glass thickness. Matrials that are low-coast are likely to have been used in its constructionFilters with nanocoatings, multi-coatings, and non-coatings
Even high-quality optical glass will have a reflection rate of approximate reflection, filter manufacturers use various types of coating.
There are currently three main types of filter coatings available.
Filters without coatings
In the absence of such a coating filter, if you use high-quality optical glass, you will receive a reflection rate of approximately 5%. With a non-coated filter, it will be more affected by lens flares and ghosting. Multi Coating Filters Most of the me You will receive a reflection rate of approximately 5% if the filter of high-quality optical glass. The coating can reduce the reflect Nanocoating Filter Nanocoating is you will receive a reflection rate of approximately 5% if the filter of high-quality optical glass.
Coating technology used in some counterfeit UV filters Be careful. A high-quality optical glass filter will have a reflection rate of approximately 5%. There is no doubt that it is a counterfeit product from China.
Make sure you buy your optics from reputable retailers. Stay away from eBay and AliExpress
A high-quality optical glass UV filter will have a reflection rate of approximately 5%.
However, purchasing a $100 UV Filter in order to protect a $150 kit lens would not be practical. Due to the fact that inexpensive lenses. As they are not constructed using the highest quality glass and coatings. The light transmission of these lenses is already low. It is unlikely that the expensive protective UV filter will be able to correct the lens flaws and imperfections.
It is fortunate for us that there is a simple rule of thumb in photography. An average UV protection filter costs 10% of the cost of the lens, according to the article.
As a conclusion
If you shoot with a $1000 quality lens, you will need to spend approximately $100 to match its quality.
As far as I am concerned, the rule works pretty well for me. A $40 Tiffen UV protection filter will be enough if you shoot with a $300-400 lens.
A UV protection lens filter was invented to fix this problem. UV filter camera lens modifiers reduce the amount of ultraviolet light emitted by the camera lens. UV light has become less problematic with the introduction of digital technology in DSLR cameras and mirrorless cameras.
