## Description

K&F Concept 40.5mm Neutral Density Filter, 40.5mm Slim Variable Fader ND Filter Adjustable ND2 to ND400 Filter + Cleaning Cloth

## Features

- 【Import Optical Glass】Crafted from premium AGC optical glass with 8 multi-layer coatings, this ND filter reduces reflections and glare, ensuring superior image quality.
- 【Versatile Light Control】With 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, this filter is perfect for diverse scenarios. (Note: Max stops may cause a cross-pattern effect, commonly known as an "X black cross." This phenomenon is natural and temporary, occurring due to the adjustable ND filter's interaction with specific lenses and focal lengths.
- 【Glare-Free Surface】Treated with an oxidized sandblasting process, this filter prevents unwanted stray light and minimizes unnecessary reflections on the metal surface.
- 【Slim and Secure】At a mere 7.4mm thickness, the CNC-patterned design ensures enhanced friction while rotating, making it easy to attach/detach lenses and accessories anytime, anywhere.
- 【Compatibility Note】This ND filter suits all 40.5mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, a 43mm lens cap is required for this 40.5mm variable ND filter.

## Customer Reviews

### ⭐⭐⭐⭐⭐ So what type of magic is this anyway?! 😂
*by M***A on August 27, 2024*

This is the coolest filter I have ever purchased for a camera. Okay, so it's not magic, but to be honest it might as well be. I have no clue how it works but it is the smoothest transition from each level. It goes from barely there to extremely dark in a smooth transition just by slowly turning the dial. Way cool, practical and perfect! Image quality through it is great. Don't hesitate to buy this. Also, fyi, you can buy a OEM cap to fit it. The listing has the lens cap size in the description so I ordered a lumix cap in that size and it fits perfectly. You will want one so you can leave the filter on without issue.Also, a word of CAUTION!! Don't put this on with an auto close cap!!! It jacked my camera up and I was afraid it was gonna be wrecked. Took some finagling but I finally got the filter off and restarted camera and it fixed the error. But it was scary!! So be sure to have the auto cap removed before using! These filters do not work with an auto cap!

### ⭐⭐⭐⭐⭐ Excellent Quality for Photography and Videography!
*by P***S on March 16, 2025*

The K&F Concept 67mm Variable ND2-ND400 Filter is an outstanding addition to my camera gear! It provides excellent control over exposure, allowing me to shoot in bright conditions while maintaining proper image quality. The filter is well-built, easy to adjust, and produces smooth, even results without any noticeable color shifts. Whether you’re a photographer or videographer, this filter is a must-have for achieving great shots in varying light conditions. Highly recommend!

### ⭐⭐⭐⭐⭐ Great filter!
*by R***L on June 12, 2025*

I purchased this for use on my iPhone 15 pro max for content creation. Videos and photos. This filter is great. I am a newb at photography. But I noticed a difference in photos when taking pictures! If it worked great for my phone. It would work great for an actual camera! Highly recommend!
