Kenko 37-43mm Step-Up Ring

Introduction

This Kenko 37-43mm Step Up Ringallows the use of 37mm filters and accessories on a lens with a 43mm filter thread. The Step Up Ring attaches to the front of a lens, and converts the thread size of your lens to the thread size of any other accessory (such as filters, hoods, flashes and lens converters). The first number is always the lens thread size, the second number is the filter size of the accessory. If the first number is bigger, it’s a step-down ring. If the first number is smaller, it’s a step-up.
