---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- [NANO-K Variable ND Filter] The K&F CONCEPT ND2-ND400 variable ND filter has nine adjustable levels of light output from ND2 to ND400, allowing you to adjust the density of the neutral density filter as needed to adapt to various lighting conditions. (Note: This variable ND filter is not suitable for use with telephoto lenses. Lens hoods cannot be attached.) While there is a mix of old and new exteriors, the internals are identical. [18-Layer Coating] The variable ND filter is made of high-quality optical glass with 18 layers of transparency-enhancing coating on both sides, which can effectively reduce reflected light on the filter surface. [Self-developed Lens Cap] This high-quality lens cover features an innovative non-spring structure to prevent spring deterioration and other issues. The inner structure design allows it to be attached to a variety of lenses. [Includes one vacuum-sealed cleaning cloth] The included cleaning cloth is made of microfiber and will not damage the coatings on lenses, lens filters, or other optical devices. It can also thoroughly remove stubborn oil and sebum stains. [Note] *️Variable ND filters are prone to X-shaped unevenness when set to the higher setting. The location of the unevenness will vary depending on the type of lens and focal length used. If you continue to rotate the filter, the shadow will naturally disappear. This is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND. *K&F CONCEPT is the world's No. 1 brand in terms of lens filter online sales volume among camera-accessory-focused brands.
