Concept 37mm Variable ND Filter Made in Japan AGC Optical Glass 18 Layer Coating Water Repellent and Stain Resistant Thin Lens Filter for Photography

[Variable ND Filter] 37mmmm K&F Concept variable ND2-ND400 filter. Compatible with 37mm size lenses, please check the lens size in advance. Since it has a double structure, if the variable ND filter is 37mm, the lens cap will be 40.5mm. [Dimming range ND2-ND400] Light intensity can be adjusted in 9 levels from ND2 to ND400, and can be used in a wide variety of places with just one ND filter. When shooting moving scenes such as waterfalls or clouds with high-speed film or digital cameras, it is possible to widen the aperture and lower the shutter speed, making it possible to express a mountain stream as smoothly as a sea of clouds. It is very useful in a wide range of shooting scenes such as the ocean, lakes, and clouds, allowing you to take professional-looking landscape photos. [Reduced Reflection/Excellent Material] The 18-layer coated optical glass reduces reflection, allowing you to express the scenery seen through the water, the scenery reflected on the water surface, and the transparency of leaves wet with water. Adopting a metal frame, it has excellent durability and wear resistance, and is lightweight and easy to carry. [Note] Depending on the amount of light in the shooting environment, variable filters may cause X-shaped unevenness when using the maximum level of ND400. 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. Thank you for your understanding. Our X-shaped unevenness control filter is also available. (X-shaped unevenness control filter: ND2 to ND32, ND8 to ND128) ⚠️This variable ND filter is not suitable for use with telephoto lenses. This product will be randomly shipped in new and old packaging, but please note that the quality of the contents will not change. If you receive a package that is different from the product image, please use it with confidence. ⚠️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.
