B+W 65-069439 Stepdown Ring 67mm to 62mm

The B+W 65-069439 Step-Down Ring provides a simple, reliable way to mount 62mm-threaded filters onto lenses with a 67mm filter thread. Manufactured from high-quality aluminum, the ring offers precise machining that ensures smooth threading and a secure fit without the risk of cross-threading or seizing. The engraved size markings on the outer edge make it easy to identify the ring at a glance, even when it is already mounted on a lens—a practical detail when working with multiple adapter rings in a kit.

This adapter uses the standard 0.75mm thread pitch that is universal across photographic filters in these sizes, ensuring broad compatibility with filters from any manufacturer. It is an economical solution for photographers who already own a set of 62mm filters and want to use them on a 67mm-thread lens without purchasing duplicate filters in the larger size. However, because the ring adapts to a smaller diameter, users should be aware that vignetting may occur at wider focal lengths where the smaller filter diameter encroaches on the lens's field of view.
