L’adattatore si avvita semplicemente sulla filettatura frontale dell’obiettivo (55 mm) e consente di utilizzare filtri più grandi come **UV, CPL o ND da 77 mm** senza problemi. La costruzione in **lega di alluminio anodizzato** è leggera ma abbastanza robusta, e le filettature sono precise: l’anello entra facilmente e i filtri si avvitano senza impuntamenti. Questo tipo di adattatore è ideale per **standardizzare i filtri su un diametro più grande**, evitando di acquistare lo stesso filtro in più misure. ([Walmart.com][1]) Nella confezione sono inclusi **due anelli**, utile se si hanno più obiettivi o come ricambio, oltre a un **panno in microfibra** per la pulizia delle lenti. Pro: costruzione in metallo leggera e resistente filettature precise e facili da montare permette di usare filtri da 77 mm su obiettivi da 55 mm confezione con due anelli + panno di pulizia Contro: con alcuni obiettivi il paraluce originale potrebbe non essere più utilizzabile Nel complesso è un accessorio economico ma molto pratico per chi usa filtri fotografici e vuole ridurre il numero di diametri diversi nel proprio kit. ## Frequently Bought Together - K&F Concept 49-52mm(2 Pcs) Step-Up Ring Adapter, 49mm to 52mm Step Up Filter Ring for 49mm Lens Install 52mm ND CPL UV Lens Filter - K&F Concept 52mm 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 52mm 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.pt/products/650192039-k-and-f-concept-49-52mm-2-pcs-step-up](https://www.desertcart.pt/products/650192039-k-and-f-concept-49-52mm-2-pcs-step-up) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-28*
