Frequently Asked Questions

The primary purpose of this adapter ring is to allow you to use filters with a larger thread diameter (46mm) on a camera lens that has a smaller front thread (40.5mm).
This specific adapter allows you to attach a 46mm filter to a camera lens with a 40.5 mm front thread.
"Step-up" means the adapter increases the diameter from the lens thread (40.5mm) to the filter thread (46mm), allowing a larger filter to be mounted.
While designed to be compatible, generally, stepping up to a larger filter size is less likely to cause vignetting than stepping down, but it can depend on the lens's focal length and design.
This adapter is specifically designed for lenses with a 40.5mm front thread and filters with a 46mm thread; it is not universally compatible with all lens and filter sizes.
A step-up ring helps photographers save money by allowing them to use a single set of larger filters across multiple lenses with different thread sizes, rather than buying dedicated filters for each lens.
