The Urth 49-55mm step up ring lens filter adapter enables photographers to use 55mm threaded filters on camera lenses with 49mm filter threads. This precision-machined adapter is constructed from durable aluminum alloy with an anodized black finish that resists corrosion and maintains a lightweight profile. The adapter measures approximately 3mm in thickness, adding minimal bulk to your lens setup while ensuring secure filter attachment. With a weight of approximately 15g, it provides a practical solution for expanding filter compatibility without significant added weight. The step-up ring features precise threading that ensures smooth attachment and removal, minimizing the risk of cross-threading or damage to your lens filter threads. This adapter is designed for photographers who own multiple lenses with different filter thread sizes, allowing them to standardize their filter collection to the larger 55mm size. The Urth 49-55mm step up ring maintains optical quality by providing a secure, flush connection between lens and filter, preventing light leaks or vignetting that can occur with poorly fitted adapters.
