The 46mm-37mm ring adapter easily screws onto the front of any 46mm lens, and converts the thread size of your lens to the thread size of any other 37mm accessory (such as filters, hoods and lens converters).

Features:
1. Simply screw the step-down ring into the lens threads and tighten for quick installation and removal.
2. Has a black coated design that makes it match and harmonize with most camera equipment as a whole.
