Ive so far oreded a few items from K&F CONCEPT and I got to say their product is really good so far. The lens filter is just as described and I love the matt finish of the material used. The material used feels high quality and feels really durable all for a good reasonable price! Its not too heavy very light weight and was able to install on to my lens with no issues. Now there is plenty more positive things to say but, I just have a couple of things that I found personly disappointing/annoying when using the lens filter. Cons: 1. The lense filter sits properly but you loose the ability to use your lens cap. Id have to remove the filter and place lens cap where as other filters I was able to keep on my lens and still place the cap on. 2. The dial to choose how much of the ND filters to use just continues to spin I feel like when shooting having to continuously look where im setting it too will become tedious. Id suggest having stoppers when reached max or min and to possibly have groves to feel what setting im on like slight click in between each "setting". But thats just me being annoying and picky lol. Aside from the "negative" opinions I will be buying more products from this brand. As it is I am currently waiting on a lense cap with UV filter for one of my other lens and I cant wait to receive it. Review: So what type of magic is this anyway?! 😂 - 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! ## 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 12,695 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 ### ⭐⭐⭐⭐⭐ Good quality items for reasonable price. *by M***E on July 7, 2026* As an intermediate photographer thats most of the time on a budget Ive found this company to have some good quality stuff for a fraction of the price most big name brands sell them for.

A lot of my photos came out blurrier than I expected. It was on a golf course, and shooting at 1/1000, so I understand some of the action shots could be blurry. But some of the pictures where they were just standing or walking slowly were also blurry. I couldn't increase my shutter speed too much more, as the preview was coming up really dark, even with the filter all the way on Minimum. In retrospect, I could have just increased shutter speed and not used the filter. Maybe for video, but don't think it was needed for photo. By the way, this one is not compatible with the magnetic ring. ## Frequently Bought Together - K&F Concept 77mm Variable ND2-ND400 ND Lens Filter (1-9 Stops) for Camera Lens, Adjustable Neutral Density Filter with Microfiber Cleaning Cloth (B-Series) - K&F Concept 77mm Circular Polarizer Filter Ultra-Slim 18 Multi-Coated Optical Glass Circular Polarizing Filter for Camera Lenses with Cleaning Cloth (K Series) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/69232001-k-and-f-concept-77mm-variable-nd2-400-lens-filter](https://www.desertcart.no/products/69232001-k-and-f-concept-77mm-variable-nd2-400-lens-filter) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-20*
