The polarizing filter (CPL filter) and the MC UV filter have 28 layers of green anti-reflection nanotechnology coating. They are made of optical glass, HD quality, waterproof, scratch-resistant, oil-resistant. The frame surface features CNC precision engraving with non-slip teeth for precise filter adjustment. The frame thickness of the CPL filter is 5 mm, that of the UV filter is 3 mm, and the ultra-thin frame design prevents darkening when using wide-angle lenses.

CPL features include removing reflections from non-glass surfaces, removing water reflections, increasing color saturation, giving the image a blue sky and white cloud layers, and does not affect the sharpness of the image in the telephoto area, so high-resolution images can be captured.

The UV filter protects the lens from damage and absorbs UV rays. The multi-layer coating allows light to pass through without changing its direction, does not affect sharpness in the telephoto area, and produces high-resolution images. Light transmission can be up to 99.6%.

The metal lens caps are made of aviation-grade aluminum alloy and provide effective protection for the filter and lens. A storage bag is also included in the kit to help protect and store the filter on the go.

The UV+CPL+cap set includes an MC UV filter, a CPL filter, an upper and a lower lens cap, and a storage bag.

Using the MCVU and CPL at the same time is significant because you can usually always attach the UV filter to the lens (for shooting outdoors under the sun and can also be used to protect the lens), while the polarized filter can be used to eliminate non-metallic reflections, high-fidelity images and real used to reset colors.

If the polarizer (CPL) cannot be removed after the lens is installed, the metal ring in front of the CPL must be rotated, and then you can use a cleaning cloth and rubber band to increase the friction to remove it.

In order to choose the right filter size, the size shown next to the diameter symbol on the front of the lens should be taken into account.

The threaded cap can also be used with other filters or lenses. AGC optical glass provides greater clarity and color fidelity. Glass with 28 layers of nanometer coating on both sides is waterproof and scratch-resistant. The thin aluminum frame reduces vignetting.
