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.
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.

Question: Will this ring let me use a 77mm filter on my 49mm lens?
Answer: Yes. The 49-77mm step-up ring adapts a 49mm lens thread to accept 77mm filters and other threaded accessories.
Question: What does the inside anti-reflective treatment do?
Answer: The product includes an anti-reflective treatment on the inside of the ring to help manage stray light inside the adapter; this feature is part of the ring’s design.
Question: Is the ring easy to screw on and remove?
Answer: The knurled sides provide a firmer grip, making it easier to mount and remove the adapter by hand.
Question: Can I use this with any filter brand that has a 77mm thread?
