The NiSi Step-Up Adapterring Brass 55-58mm lets you mount camera accessories with a larger thread diameter than your lens filter thread. In practice, you screw the adapter onto a 55mm lens thread and then attach a 58mm filter or other accessory. This simple conversion increases your filter options without changing lenses.
Use the adapter by screwing the 55mm side onto your lens filter thread first. Then, thread a 58mm filter or accessory onto the larger 58mm side. This method allows you to use larger-diameter filters on lenses with smaller filter threads without modifying the filter or lens.
For example, if you have a 77mm lens thread and want to fit an 82mm filter, you would use a NISI STEP-UP ADAPTERRING TI 77-82MM. The same numbering rule applies: the first number is your lens thread and the second number is the filter thread.
First, you expand compatibility between lenses and filters, which helps when you own filters in several sizes. Second, you gain a firmer handling experience because of the knurled sides. Finally, the interior anti-reflective treatment helps maintain image quality by minimizing stray reflections inside the adapter.

Question: What do the numbers 55-58 mean?
Answer: The first number (55) indicates the thread size of your lens, and the second number (58) indicates the thread size of the filter or accessory you want to attach. The adapter lets you use a 58mm filter on a 55mm lens.
Question: What is the adapter made of and why does that matter?
Answer: The adapter is made of high quality brass. Brass provides durable mechanical strength for repeated mounting and removal. In addition, the knurled sides improve grip when you screw the ring on or off.
Question: Why does the inside of the ring have an anti-reflective treatment?
Answer: The anti-reflective treatment on the inside of the ring helps reduce internal reflections that could otherwise affect image contrast. This finish supports cleaner images when using the adapter between your lens and filter.
Question: How do I choose the right step-up ring for other sizes?
Answer: Match the first number to your lens thread and the second number to the filter thread you wish to use. For instance, to fit an 82mm filter on a 77mm lens, you would use the NISI STEP-UP ADAPTERRING TI 77-82MM. Follow the same rule to select other step-up rings.
