Concept 72mm Variable ND Filter Dedicated Filter Cap Included Japanese AGC Optical Glass 18 Layer Coating Water Repellent Stain Resistant Thin Lens

[Excellent Material] The cap is made of soft silicone material, which is smooth to the touch, waterproof, and dust and stain resistant. Even though this filter uses tempered optical glass with an 18-layer coating, it achieves a high transmittance of 99.6% without affecting the color of the photo. [Easy to put on and take off] The cap is elaborately processed, can be put on and taken off with one touch, and fits perfectly to the lens. Since there are no gaps, dirt and dust are prevented from entering. Provides strong protection for omnidirectional filters. [Excellent Protection] The cap is made of silicone material, and has better impact resistance than ordinary caps, such as preventing scratches and falling. The filter has a water-repellent (WPC) finish, allowing for safe and stable shooting even in harsh shooting environments where dirt and water droplets can be easily removed, such as near water, in the mountains, or in the forest. Fingerprint-resistant, easy to wipe off even if it gets dirty, and protects your precious lens. [Note] This cap can only be attached to the filter while the variable ND filter is attached to the lens. It cannot be attached directly to the lens. Also, filters such as CPL filters and UV filters cannot be installed directly. Please be very careful! This lens cap is only compatible with K&F variable ND filters (excluding high resolution ND2-400).
