CONCEPT 72mm Variable ND Filter Lens Filter for Light Reduction K&F ND2-400 Ultra-thin

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

This listing is for a 72mm K&F CONCEPT variable ND filter from the NANO-B series, complete with a cleaning cloth. Because variable ND filters have a double-layer structure, the lens cap will be 77mm when the filter is 72mm. While the exterior may be a mix of old and new designs, the internal components are identical. [Neutral Density Filter] ND filters can reduce the amount of light and prevent overexposure when shooting during the day. Because they are variable, you can adjust the light intensity from ND2 to ND400. This is very convenient as you don't need to carry multiple filters. They can create the effect of thread-like water flow or light cascades, and can be in various scenes such as streams, oceans, and waterfalls. [Precautions] When the amount of light reduction exceeds a certain point (when adjusted to ND400) (near the MAX), X-shaped unevenness or a bluish tint may occur. This is normal, so please be aware of this in advance. If you continue to rotate the filter, the shadow will disappear naturally. This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND filter. By using an ND filter to reduce light, you can broaden your range of aperture and shutter speed choices, and sometimes achieve more ideal color reproduction. It can create the effect of thread-like water flow or light flow, and can be in various scenes such as streams, oceans, and waterfalls. This variable ND filter cannot be for telephoto photography, but the NANO-X series ND2-400 filter can be with lenses with a focal length of 300mm. The ASIN for the 72mm NANO-X series ND2-400 filter is B0915KF9BP. [NANO-B Series Variable ND] This is a 72mm K&F Concept variable ND filter with a cleaning cloth. Because variable ND filters have a double-layer structure, the lens cap will be 77mm when the variable ND filter is 72mm. *Note: While the exterior may be a mix of old and new designs, the internal components are identical.
