K&F CONCEPT Magnetic CPL Filter 52 mm Circular Polarising HD Optical Glass with Multi Nano Coating (Nano Xcel)

Please note: 1. This kit is not compatible with K&F CONCEPT filters or adapters of the same size. A1 magnetic filter set is only with A1 magnetic adapter. 2. The magnetic adapter must be installed before installing the magnetic filter. (Magnetic filters must be used with a magnetic adapter.) Function: With circular CPL filters, you can use unwanted reflections from non-metallic surfaces such as water, glass, etc., improves colour saturation and contrast. This effect is commonly used to increase contrast and saturation in blue skies and white clouds. (Note: New and old packaging will be sent randomly.) Install and remove one second: Magnetic attraction helps to install the filter in one second, reduces scratches and damage to the lens thread, 5.3 mm ultra-slim CNC non-slip aluminum-magnesium alloy frame grips the filter easily and no vignetting on wide angle lenses. Import optical glass: Round CPL filter made of Japanese AGC glass, the base refraction index of only 0.2%, high-quality glass that ensures image quality and sharpness. 28 multi-layer coatings: both sides of the glass with nanometer coatings, abrasion-resistant and hydrophobic coatings increase surface hardness and make cleaning easier. Kit includes: Package with 1 x magnetic CPL filter + 1 x magnetic filter adapter ring + 1 x filter lens cap. Note: this filter only fits lenses of the same size, 49mm filter can only be installed directly on 49mm lenses. Please check your lens size, this number is always preceded by a "Ø" (diameter) symbol. Example: Ø49 = 49 mm lens thread size.
