Variable ND filters also have limited application with wide angle lenses (they can only be used to about the halfway mark of Min and Max markings because the field of view is so broad). For a wide-angle lens, we suggest using fixed ND filters or ND2-32 or ND8-128. You can also try adjusting your focal length and reducing the density (rotating back towards the ‘Min’ mark) until the colour shift disappears. **Q: If i rotate the density from nd2 to nd400 and have a lens hood connected to the 77mm front threads, will the hood move?** A: hello, for the 77mm nd filter ,the lens hood size should be 82mm for the 72mm nd filter , the lens hood size should be 77mm. by the way, when you use a nd filter , you better not add a lend hood ,the lend hood should move. **Q: Can i still return it if i opened one of the cloths?** A: Yes, you may return it; as long as it's in your 30 day window to return it. ## Frequently Bought Together - K&F Concept 37mm ND Fader Variable Neutral Density Filter ND2 to ND400 for Camera Lens Ultra-Slim, Multi Coated - Smartphone Camera Lens Adapter Ring, 17mm to 37mm, Stainless Steel, Moisture-Proof, Waterproof, Easy to Mount and Remove --- ## 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.is/products/270700460-37mm-nd-fader-variable-neutral-density-filter-nd2-to-nd400](https://www.desertcart.is/products/270700460-37mm-nd-fader-variable-neutral-density-filter-nd2-to-nd400) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-26*
