(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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N3N6GT0 | | Best Sellers Rank | #1 in Camera Lens Neutral Density Filters | | Brand | K&F CONCEPT | | Coating Description | Multi Coating | | Compatible Devices | Cameras with 40.5mm lens thread size | | Customer Reviews | 4.5 4.5 out of 5 stars (12,601) | | Enclosure Material | Optical Glasses,Resin | | Item Dimensions L x W | 1.59"L x 1.59"W | | Item Weight | 0.27 g | | Manufacturer | Shenzhen Zhuoer Photograph | | Manufacturer Part Number | SKU.0885V1 | | Media Type | ProductImage | | Model Number | AMSKU0885 | | Number of Items | 1 | | Photo Filter Size | 40.5 millimeters | | Screen Size | 40.5 millimeters | | Set Name | K&F Concept 40.5mm Neutral Density Filter Set | | Special Effect | Neutral Density | | Thread Size | 40.5 millimeters | | UPC | 700424384280 | | Unit Count | 1 Count | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** K&F CONCEPT - **Coating Description:** Multi Coating - **Item Highlight:** Ultra Slim Adjustable Neutral Density Filter with Microfiber Cleaning Cloth (B-Series) FN101 - **Material:** Optical Glasses,Resin - **Photo Filter Effect Type:** Neutral Density - **Photo Filter Size:** 40.5 millimeters - **Photo Filter Thread Size:** 40.5 millimeters - **Product Dimensions:** 1.59"L x 1.59"W - **UPC:** 700424384280 - **Water Resistance Level:** Not Water Resistant ## Images ![K&F Concept 40.5mm Neutral Density Filter, 40.5mm Slim Variable Fader ND Filter Adjustable ND2 to ND400 Filter + Cleaning Cloth - Image 1](https://m.media-amazon.com/images/I/71qihoL1+lL.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 ## Frequently Bought Together - K&F Concept 40.5mm Neutral Density Filter, 40.5mm Slim Variable Fader ND Filter Adjustable ND2 to ND400 Filter + Cleaning Cloth - Screen Protector for Sony Alpha ZV-E10 ZVE10 ZV-1F ZV1F ZV-1 II ZV-1 ZVI ZV1II [Not for ZV-E10 II]Camera & Hot Shoe Cover ,ULBTER 0.3mm 9H Hardness Tempered Glass Cover Anti-Scrach Anti-Bubble [3+2 Pack] - SMALLRIG ZV-E10 Cage with Silicone Handle and Built-in Threaded Holes, Cold Shoe and Quick Release Plate for Sony ZV-E10 --- ## 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.pt/products/12999622-k-and-f-concept-40-5mm-neutral-density-filter-40](https://www.desertcart.pt/products/12999622-k-and-f-concept-40-5mm-neutral-density-filter-40) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-03*
