55mm UV Protective Filter for Sony Alpha a7 III Mirrorless Digital Camera with 28-70mm Lens, a6600 Camera with 18-135mm Lens If there is only one accessory you will purchase for the lens of your camera or camcorder, this should be the one. A UV filter serves to protect your lens from all dust, dirt, scratches and fingerprints. - Helps eliminate bluish cast in images It also absorbs the Ultraviolet rays of the sun thereby reducing or eliminating distortion. Prevents loss of sharpness and contrast by filtering out UV rays ur filters are manufactured from the finest solid optical glass, and are heat treated and multi-coated to ensure optimum picture quality. - Please verify your camera's lens thread size before ordering. Your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a "Ø" (diameter) symbol. Filter compatible with many other lenses that have a 55mm thread:

What is UV (ultraviolet) light?
The visual spectrum—the light we see with our eyes—consists of the colors red, orange, yellow, green, blue, indigo and violet. Mix them together and you get “white” light. The electromagnetic wavelengths of light are measured in terms of nano-meters (nm), with the visual spectrum residing in the 390 to 750nm portion of the electromagnetic bandwidth. Just below the red end of the visual spectrum is infrared (approx 750nm to 1mm) and ultraviolet light resides just above the blue end of the visual spectrum (approx 10nm to 390nm). While we cannot see UV light, it nonetheless impacts the visual quality of the pictures we take.

In the days of film the value of placing a UV filter in front of your lens was never questioned. In addition to dampening the image-robbing effects of atmospheric ultraviolet radiation, UV filters also served to protect the front element of your lens from dust and moisture. They also repelled the inevitable smudges and scratches that over time compromise the effectiveness of the anti-reflective coatings that go into determining how well (or not so well) your pictures turn out. Fast-forward to the modern days of digital imaging and the big argument is: “do we still need UV filters?” The answer is an unqualified “Yes.” Despite the fact that digital imaging sensors are nowhere near as sensitive to UV radiation as film, the protective properties of a UV filter on your lens are still quite justified. Regardless of how the image is being recorded, the probability of dust, moisture, smudges and scratches finding their image-compromising way onto your front lens element is equally inevitable and troublesome.

All our filters are carefully formulated to ensure consistent color and accuracy throughout the entire surface of the glass. Why? Consistent color means consistent high quality results.
