Key features
- Material: Made of high quality Brass.
- Grip: Knurled sides provide a firmer grip when attaching or removing the ring.
- Inner treatment: The inside of the ring has an anti reflective treatment.
- Function: A step-up ring allows you to fit a filter that has threads larger than your lens.
- Thread notation: The first number indicates your lens thread and the second number indicates the filter thread.
How the adapter ring works
Use the step-up adapterring when you want to use a larger filter on a lens with a smaller filter thread. For example, the product name 49-58mm means the adapter fits a 49mm lens thread and accepts a 58mm filter thread. The original text also shows a similar 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.
Why these details matter
Knowing the two thread numbers helps you select the correct adapterring. The knurled sides help when you mount or remove the ring by hand, and the anti reflective treatment on the inside is a specified feature of this NiSi brass ring.
