【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.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
[NANO-K Variable ND Filter] The variable ND filter of K&F Concept ND2-ND400 can adjust the light intensity in 9 levels from ND2 to ND400, and the density of the neutral density filter can be adjusted at any time as needed to adapt to different light environments. (⚠️This variable ND filter is not suitable for use with telephoto lenses. A lens hood cannot be attached.)
[18-layer coating] The variable ND filter is made of high-quality optical glass with 18-layer transparency-enhancing coating on both sides, which can effectively reduce the reflected light on the filter surface.
[In-house developed lens cap] Comes with a high-quality lens cover and adopts an innovative non-spring structure to avoid problems such as spring deterioration. The inner-type structural design allows it to be attached to fit a variety of lenses.
[Includes 3-piece vacuum packaging cloth] The included cleaning cloth is made of microfiber and will not damage the coating of optical equipment such as lenses and lens filters. Even stubborn oil films and sebum stains can be easily removed.
[Note] ⚠️If the variable ND filter is on the high stage side, X-shaped unevenness is likely to occur. The location of the unevenness varies depending on the type of lens used and focal length. Keep rotating the filter and the shadows will disappear naturally. This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND.
