It's been a durable design at a very affordable price. It fulfills everything that it said it would and is easy to install and use. My images are still very clear and not cloudy as I use the filter. It makes a huge difference in my image using this filter to help reduce the harsh light coming into my camera. There is a slight vignette on the image, but not drastically noticeable. The only downside is the lack of gauges to keep track of what stop the filter is at. It requires you to watch the LCD screen as you turn the knob on the filter. Still happy with the product, but wish there were numbers on the filter. Overall, highly recommend, especially for the price! Review: Works great - Works great I use it with my Sony Zv-E10. Easy to install.portable lens's cap nice case. Fits perfect in my case. Perfect compatibility. Wish it had a lens cap to keep it covered when moving around. ## 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 77mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, a 82mm lens cap is required for this 77mm variable ND filter. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DNSK4WS | | Best Sellers Rank | #1 in Camera Lens Neutral Density Filters | | Brand | K&F CONCEPT | | Coating Description | Multi Coating | | Compatible Devices | All 77mm lenses | | Customer Reviews | 4.5 out of 5 stars 12,636 Reviews | | Enclosure Material | Optical Glass | | Exposure Control Type | Manual (M) | | Item Dimensions L x W | 3.03"L x 3.03"W | | Item Highlight | Ultra Slim Adjustable Neutral Density Filter with Microfiber Cleaning Cloth (B-Series) FN101 | | Item Weight | 0.27 g | | Manufacturer | Shenzhen Zhuoer Photograph | | Manufacturer Part Number | BRDFSKU0129 | | Material | Optical Glass | | Model Number | DFSKU0129 | | Number of Items | 1 | | Photo Filter Effect Type | Neutral Density | | Photo Filter Factor | 400 x | | Photo Filter Size | 7.7 centimeters | | Photo Filter Thread Size | 7.7 centimeters | | Screen Size | 7.7 centimeters | | Set Name | 77mm | | Special Effect | Neutral Density | | Thread Size | 7.7 centimeters | | UPC | 681013891115 | | Unit Count | 1 Count | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** K&F CONCEPT - **Coating Description:** Multi Coating - **Material:** Optical Glass - **Photo Filter Effect Type:** Neutral Density - **Photo Filter Factor:** 400 x - **Photo Filter Size:** 7.7 centimeters - **Photo Filter Thread Size:** 7.7 centimeters - **Product Dimensions:** 3.03"L x 3.03"W - **UPC:** 681013891115 - **Water Resistance Level:** Not Water Resistant ## Images ![K&F CONCEPT 77mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens - Image 1](https://m.media-amazon.com/images/I/71sJ17dd4tL.jpg) ![K&F CONCEPT 77mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens - Image 2](https://m.media-amazon.com/images/I/71I2YbnBtDL.jpg) ![K&F CONCEPT 77mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens - Image 3](https://m.media-amazon.com/images/I/51hT1ZfkVLL.jpg) ![K&F CONCEPT 77mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens - Image 4](https://m.media-amazon.com/images/I/61NK5CMIhrL.jpg) ![K&F CONCEPT 77mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens - Image 5](https://m.media-amazon.com/images/I/712OZFHUmbL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can I use the lens hood after using the adjustable ND filter?** A: No, it couldn't **Q: Is it possible to install a lens cap?** A: Yes, but need larger than filter **Q: Can I overlay other filters?** A: Don't suggest add other filters **Q: How to avoid vignettes?** A: Continuing to rotate the shadow will disappear naturally. **Q: Is it compatible with magnetic filters?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great item - especially for the price *by A***. on July 31, 2025* I've been very impressed with this item for the past 2ish years.
