UV filters block UV light from reaching your camera sensor, protect your lens, and help improve sharpness in your photographs.
UV Filters cut out haze and blue cast by blocking UV light. They help improve sharpness and clarity in your photographs and protect your camera lens from scratches, dirt, dust, and grime. Using a UV filter doesn’t affect your camera settings, which means you can leave it on your lens at all times. And if you happen to drop your lens or something scratches the lens glass, a lens filter can be the difference between buying a new filter and spending hundreds or thousands of dollars to replace a lens.
