NiSi Step-Up Adapterring Brass 49-77mm – Mount 77mm Filters on 49mm Lens Threads

This NiSi Step-Up Adapterring Brass 49-77mm lets you use camera accessories and filters that have a larger thread diameter than your lens filter thread. It provides a simple way to adapt lenses with a 49mm thread to accept 77mm filters and other threaded accessories.

Key features

• High quality brass construction – the ring is made of brass for reliable threading and durability.
• Knurled sides – the textured sides give a firmer grip when mounting or removing the ring.
• Anti-reflective treatment inside – the inner surface is treated to reduce internal reflections.
• Simple step-up function – allows mounting of accessories with a larger thread diameter than the lens filter thread.

How it works and how to read the numbers

A step-up ring adapts your lens filter thread to a larger filter thread. The two numbers indicate thread sizes: the first number is the lens thread and the second is the filter thread. For example, 49-77mm means the ring fits a 49mm lens thread and provides a 77mm thread for filters and accessories.

As a general example found in product literature: 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. This demonstrates the same principle applied by the 49-77mm ring.

Usage tips

• Screw the step-up ring onto the lens' filter thread first, then attach the desired 77mm filter or accessory to the ring.
• Use the knurled sides to tighten or loosen the ring for a secure, easier grip.
• Confirm both lens and accessory threads are standard photographic filter threads to ensure compatibility.
