Review: 低価格 - 初めてＮＤフィルターを使いますが低価格でしたので購入しました。減光量はダイヤルの目印調整できますので色々と試しながら使用します。練習用には良い価格だと思います。
Review: 動画でも後ボケ成功！ でも．．．。 - 動画でも絞りを使った後ボケを試したくって、入門用に買ってみました。 一応後ボケには成功！ でも画面の右上と左下にケラレが発生。 このＮＤを使うならワンサイズ大きな物にして、ステップアップリングを併用した方が良いかも。 色合いはこれから検証します。

## Features

- 【Nano-Basic Variable ND Filter】The K&F CONCEPT ND2-400 Filter is a variable ND filter that allows for continuous adjustment of light reduction from 1-stop to 9-stops Using a neutral density filter allows you to control exposure and enhance the expressiveness of your photography Please note: If the variable ND filter is 37mm, the lens cap will be 40.5mm The Nano-Basic filter is a non-HD lens, so it cannot be used for telephoto photography This product does not come with a hood Although the exterior may show a mix of old and new, the contents are identical
- 【Multiple dimming effects with a single filter】By utilizing a variable ND filter, you can take impressive photos of the sea with slow shutter speeds and create unique presentations of nightscapes and other landscapes Ideal for shooting scenes where exposure is subject to change during video shooting
- Optical Glass: Uses high-quality optical glass to significantly reduce reflected light on the filter surface, allowing you to take bright and colorful photos freely Can be used to prevent overexposure in single-lens video shooting, and can also be used for slow shutter shooting in still images
- Includes 3 microfiber cleaning cloths in vacuum packaging. The included cleaning cloths are made of microfiber, which will not damage the coating of optical devices such as lenses and lens filters Persistent oil film and sebum stains can be thoroughly removed
- 【注意事項】When the variable ND filter is set to a higher level, X-shaped unevenness is more likely to occur The position of unevenness varies depending on the type of lens used and the focal length Keep rotating the filter, and the shadows will naturally disappear This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND

### ⭐⭐⭐⭐⭐ 低価格
*by る***ん on January 7, 2026*

初めてＮＤフィルターを使いますが低価格でしたので購入しました。減光量はダイヤルの目印調整できますので色々と試しながら使用します。練習用には良い価格だと思います。

### ⭐⭐⭐⭐ 動画でも後ボケ成功！ でも．．．。
*by A***ー on January 11, 2026*

動画でも絞りを使った後ボケを試したくって、入門用に買ってみました。 一応後ボケには成功！ でも画面の右上と左下にケラレが発生。 このＮＤを使うならワンサイズ大きな物にして、ステップアップリングを併用した方が良いかも。 色合いはこれから検証します。

### ⭐⭐⭐ 望遠撮影NG
*by A***ー on October 27, 2025*

商品説明にあるように望遠撮影NGです。 解像感が失われ、全体が著しくボヤけます。 200mmくらいならなんとかという感じですが、レンズや再生デバイスなどによるかと思いますので、心配なら標準ズームの範囲で使うかこのNANO-Bシリーズではなく、上位のNANO-Xシリーズ（カタログスペックで300mmでも可）を選んでください。
