---------------------------------------------------------------------- 【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 is a 37mm K&F CONCEPT variable ND filter (ND2-ND400). It is compatible with 37mm lenses; please confirm your lens size beforehand. Its dual-layer construction means that if the variable ND filter is 37mm, the lens cap will be 40.5mm. While there are a mix of old and new exteriors, the internal components are identical. [ND2-ND400 Light Reduction Range] With nine levels of light intensity adjustment from ND2 to ND400, this ND filter can be used in a wide variety of situations. When shooting moving scenes like waterfalls and clouds with high-speed film or digital cameras, you can open the aperture and slow down the shutter speed to capture a stream with a smooth, sea-like effect. It's also ideal for a wide range of scenes, including oceans, lakes, and clouds, allowing you to take professional-quality landscape photos. [Reduced Reflection and Excellent Material] The 18-layer coated optical glass reduces reflections, allowing you to see underwater scenes, landscapes reflected on the water surface, and even the transparency of wet leaves. The metal frame is durable and abrasion-resistant, and lightweight for easy portability. [Please note] Depending on the amount of light in the shooting environment, the variable filter may produce an X-shaped unevenness when using the maximum ND400 setting. If you continue to rotate the filter, the shadow will disappear naturally. This is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND. Thank you for your understanding. Our X-shaped unevenness control filters are also available for sale. (X-shaped unevenness control filters: ND2 to ND32, ND8 to ND128) *This variable ND filter is not suitable for use with telephoto lenses.
