K&F CONCEPT KF01.1816 Nano Series Multifunctional 82mm HD Waterproof Scratch-Resistant Black Soft Mist 1/4&ND2~ND32 Lens Filter

Description

1.Multifunctional non forked nd2-32 & Black Soft 1/4 filter. One filter has two functions, which can be used as either a dimmer or a black soft filter.
2.The top optical glass adopts double-sided 28 layer antireflection coating on the front and back of the lens, which can effectively reduce the reflection on the filter surface and avoid ghost and other problems.
3.The glass surface is plated with "mould proof", "waterproof", "scratch proof" and "oil proof" coatings, which can be easily removed even if it is contaminated with water droplets or oil.
4.The optical glass is precisely ground and polished on both sides to ensure the stability of molecular structure. It will not affect the sharpness on the telephoto lens and ensure high-definition imaging.
5.Limit structure design to prevent X-ray problems.
6.The frame surface is designed with CNC trapezoidal pattern to ensure that consumers can increase friction in a large area when rotating, and install / remove lenses and other accessories anytime and anywhere.
7. The frame is made of aviation grade aluminum, and the thickness of the frame is only 7.4mm. The design of the thin frame ensures that there will be no dark angle between the consumer and the wide-angle end and the long focal end.
