NiSi Step-Up Adapterring Brass 67-77mm

NiSi Step-Up Adapterring Brass 67-77mm – Brass construction for fitting larger filters

The NiSi Step-Up Adapterring Brass 67-77mm lets you mount filters or accessories that have a larger thread diameter than your lens filter thread. It adapts a 67mm lens thread to accept 77mm threaded filters or accessories.

Built for reliable handling

NiSi makes this adapterring from high quality brass. The metal construction gives it durable contact with both lens and filter threads. In addition, the ring has knurled sides to provide a firmer grip when you mount or remove it, making handling easier in the field.

Optical-aware interior

The adapterring features an anti-reflective treatment on the inside of the ring. This internal treatment reduces stray reflections between the lens and the attached filter or accessory, helping to maintain image quality when you add larger threaded gear.

How the step-up ring works

• Use the ring to fit a filter or accessory that has a larger thread than your lens.
• Screw the adapterring onto your lens thread (the first number in the name).
• Then screw your larger filter or accessory into the adapterring (the second number in the name).

Understanding the size notation

The size notation indicates the lens thread first and the filter or accessory thread second. For example, a 67-77mm adapterring fits a lens with a 67mm thread and accepts a 77mm filter.

As another example from NiSi’s lineup: if you have a 77mm lens thread and want to fit an 82mm filter, you would choose the NISI STEP-UP ADAPTERRING TI 77-82MM.

Compatibility and use cases

Use this step-up adapterring when you need to fit larger filters or accessories than your lens thread allows. It provides a simple mechanical solution to match different thread sizes without changing lenses or filters.

Care and handling tips

Always screw the adapterring on gently to avoid cross-threading. Tighten by hand using the knurled sides for a secure fit. When removing, grip the knurled surface to maintain control. Keep the internal surface clean to preserve the anti-reflective treatment’s effectiveness.
