A 58mm lens cap is also required for this 55mm variable ND filter. - K&F CONCEPT is the world's No.1 brand in terms of lens filter online sales volume among camera-accessory-focused brands.

I’m just waiting to see the results when I developed the film, but I’m sure it’s gonna be fine. ### ⭐⭐⭐⭐ Not a bad filter for the price *by A***R on June 12, 2023* This is not a bad filter for the price. I took it out for a trial run doing some waterfall shots this past weekend (you can see the results attached). My overall impressions: - The picture quality was pretty good, but not always tack sharp. - It does suffer from the dreaded black X at the MAX ND setting, but no issues on the lower settings. - It was nice to be able to adjust the ND setting on the fly rather than having to swap out filters. In fact, I frequently found myself adjusting it to the MIN setting to check composition and then moving back towards MAX to take the shot. - The build quality seems good and turning the filter felt smooth and fluid. - No hard stops at MAX or MIN settings, so you have to pay attention there. - The indicator dots don't tell you what ND setting you are on, so you need to keep track. - The filter is larger on the incoming end, so the lens cap from your lens will not fit. - I notice some lens flare with the ND filter when the sun is near the viewing angle that don't show up with just the lens. Since my lens shade does not fit due to the filter end being larger, I had to manually shade the lens to make the flare go away. Overall, pretty decent for a variable ND filter. I probably wouldn't use it for professional-quality pictures, but it works for someone just wanting to try an ND filter and not wanting to have to lug around a whole set of filters on a shoot. ## Frequently Bought Together - K&F Concept 55mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) 18 Multi-Layer Coatings Adjustable Neutral Density Ultra Slim Lens Filter for Camera Lens (K-Series) - Tiffen 55UVP Slim 55mm UV Protection Filter for Camera Lens, Clear Optical Glass, Impact Resistant, MADE IN USA - Amazon Basics Circular Polarizer Camera Lens Filter - 55 mm --- ## 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.co.uk/products/202295645-k-and-f-concept-55mm-variable-nd-lens-filter-nd2](https://www.desertcart.co.uk/products/202295645-k-and-f-concept-55mm-variable-nd-lens-filter-nd2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-23*
