- Attach the extender to the lens, and then attach the camera. To detach it, reverse the order. Errors may occur if you attach the extender to the camera first.
- Extenders cannot be used more than one at a time.
- If using an extender EF2x III, the maximum aperture is then f/8 and cameras that can shoot using AF are limited. Please refer to the camera's instructions for details.
