NiSi Step-Up Adapterring Brass 40,5-46mm

NiSi Step-Up Adapterring Brass 40,5-46mm – Mount larger-thread filters on smaller lens threads

The NiSi Step-Up Adapterring Brass 40,5-46mm lets you use filters or accessories that have a larger thread diameter than your lens filter thread. It adapts a lens with a smaller filter thread to accept a larger filter thread, expanding your filter options without changing lenses.

Key features

• Made of high quality Brass for durable construction and reliable fit.
• Knurled sides provide a firmer grip for easier handling and tightening.
• Anti-reflective treatment on the inside of the ring reduces internal reflections.
• Step-up function allows you to fit a filter with a larger thread than your lens filter thread.

How the step-up ring works

A step-up ring connects a lens with a smaller thread diameter to a filter with a larger thread diameter. The adapter’s first number indicates the thread size of your lens, and the second number indicates the thread size of the filter you want to use. For example, if you have a 77mm lens thread and want to fit an 82mm filter, you would use the corresponding step-up adapter (NISI STEP-UP ADAPTERRING TI 77-82MM).

Material and handling

The adapter is made from high quality Brass. In addition, the ring features knurled sides to improve grip when mounting or removing the adapter. The interior of the ring has an anti-reflective treatment to help minimise stray reflections inside the adapter.

Practical use cases

• Use the adapter when you already own filters with a larger thread size than your lens.
• Avoid having to buy duplicate filters for different lens thread sizes by matching lens and filter threads with a step-up ring.

Answer: The first number (40,5mm) indicates the thread size of your lens, and the second number (46mm) indicates the thread size of the filter or accessory you want to attach.

question: What is the main purpose of this step-up ring?
Answer: The adapter allows you to fit a filter or accessory that has a larger thread diameter than your lens filter thread, so you can use existing larger filters with a smaller lens thread.

Answer: The ring is made of high quality Brass, features knurled sides for a firmer grip, and has an anti-reflective treatment on the inside to reduce internal reflections.

question: Can you give an example of when to use a step-up adapter?
Answer: If your lens has a 77mm thread and you own an 82mm filter, you would use the matching step-up adapter (for example, NISI STEP-UP ADAPTERRING TI 77-82MM) so the larger filter can be mounted on the smaller lens thread.
