Gloxy Step Down Ring Adapter for 49-37mm

The Gloxy Step Down Ring Adapter 49-37mm enables you to attach a 37mm filter to a lens with a 49mm filter thread. Made from lightweight, durable anodized aluminum with precisely cut threads for a secure connection.

This adapter has no optical elements and does not affect image quality or autofocus performance. Be aware that the step-down from 49mm to 37mm may cause vignetting at wider angles, so it is best used with standard to telephoto focal lengths.
