NiSi Step-Up Adapterring Brass 40,5-49mm

NiSi Step-Up Adapterring Brass 40,5-49mm – Brass construction with knurled grip and anti-reflective interior

This NiSi step-up adapterring lets you mount camera accessories that have a larger thread diameter than your lens filter thread. It provides a simple mechanical solution when you need to fit a larger filter or accessory onto a lens with a smaller thread.

What the adapter does

The adapter converts a smaller lens thread to a larger accessory thread. In practical terms, you screw the adapter onto your lens filter thread and then attach the larger threaded filter or accessory to the adapter. This way, you can use one filter size across lenses with smaller thread diameters.

Design and handling

NiSi manufactures this step-up ring from high quality brass. The ring features knurled sides to give you a firmer grip when mounting and removing it. In addition, the inside of the ring has an anti-reflective treatment to reduce internal reflections.

Sizing and compatibility

The product name shows the thread conversion: 40,5-49mm. The first number indicates the thread of your lens and the second number indicates the thread of the filter or accessory you want to fit. For example, if you have a 77mm lens thread and want to fit an 82mm filter, you would use the NISI STEP-UP ADAPTERRING TI 77-82MM.

Typical use cases

• Attach larger threaded filters to lenses with smaller filter threads.
• Use one filter size across multiple lenses when you only have smaller lens threads.
• Adapt other threaded camera accessories that require a larger diameter than the lens provides.
