1. This filter adopts AGC optical glass, and the surface of the filter has 28 layers of optical coating.
2. The 28 layer coating has ultra-high light transmittance. The coating can minimize reflection and flare and improve image quality. The hydrophobic coating also has waterproof, scratch proof and antifouling functions.
3. The frame adopts aviation grade aluminum alloy frame, and each frame weighs only 0.8g.
4. The surface of the mirror frame is treated with matte anodic oxidation, which greatly improves the wear resistance and corrosion. In addition, it can also minimize reflection and reduce the impact of reflection on imaging.
5. The back buckle is installed and positioned accurately, fits perfectly with the camera base, and is easy to install / disassemble, firm and reliable.
6. ND4&pl: dimming level 2, suitable for partial cloudy days. At the same time, it can eliminate reflection and improve saturation by 2 in 1
7. ND8&pl: dimming level 3, suitable for partial cloudy days. At the same time, it can eliminate reflection and improve saturation by 2 in 1
8. ND16&pl: dimming level 4, suitable for use in normal sunlight, at the same time, it can eliminate reflection and improve saturation by 2 in 1
9. ND32&pl: dimming level 5, suitable for use in bright fields, at the same time, it can eliminate reflection and improve saturation by 2 in 1
10. ND64&PL; Dimming level 6, suitable for use in very bright light, can eliminate reflection at the same time, and improve saturation by 2 in 1
