Canon 3563B001AA Macrolite Adapter 67 for Macro Lenses

The Canon 3563B001AA Macrolite Adapter 67 is a simple but essential accessory for macro photographers who use Canon's dedicated ring and twin flash systems. It provides the mechanical connection between the Canon MR-14EX Ring Lite or MT-24EX Macro Twin Lite Speedlites and any Canon lens featuring a 67mm filter thread, most notably the EF 100mm f/2.8L Macro IS USM. Without this adapter, the Speedlite units cannot mount to the front of the lens, making it a required component for hands-free, on-axis macro illumination.

Weighing just 20 grams, the adapter screws directly onto the lens filter thread and provides the bayonet or locking interface that the Speedlite housing attaches to. The fit is precise and secure, as expected from a genuine Canon part, and installation takes only seconds. Because the adapter occupies the filter thread, photographers who rely on protective or polarizing filters will need to remove them when the macro flash is in use. Its narrow purpose means it offers no additional features, but for Canon macro shooters it fills a critical role that no third-party workaround can reliably replicate.
