The Urth 55 72mm magnetic step up ring lens filter adapter enables seamless compatibility between lenses with 55mm filter threads and filters designed for 72mm threads. This precision-engineered adapter features a magnetic connection system that allows for quick filter changes without threading, reducing the risk of cross-threading damage to your lens. Constructed from durable aluminum alloy with an anodized black finish, it maintains a slim profile of approximately 3mm thickness to prevent vignetting while ensuring reliable performance. The adapter includes strong neodymium magnets that securely hold filters in place, yet allow for effortless removal when needed. This step-up ring is particularly useful for photographers who own multiple lenses with different filter thread sizes but want to standardize their filter collection to the larger 72mm diameter. The magnetic design eliminates the need to screw filters directly onto lenses, protecting both your lens threads and filter threads from wear over time. Compatible with all standard 72mm screw-in filters including UV, polarizing, neutral density, and special effect filters. The adapter maintains optical quality with minimal impact on image sharpness or light transmission. Ideal for landscape, portrait, and travel photographers who frequently switch between lenses and need efficient filter management. The compact design makes it easy to store in camera bags alongside your filter collection. Note that this is a step-up adapter only and cannot be used to mount smaller filters on larger lenses. Always ensure proper alignment when attaching to prevent accidental detachment. This is the successor model of previous threaded adapter designs, offering improved convenience for photographers working in dynamic shooting conditions.
