Canon Extension Tube FL 15

The Canon Extension Tube FL 15 is a vintage optical accessory designed for Canon FL breech-lock mount camera systems. Placed between the camera body and an FL mount lens, it increases the distance between the rear lens elements and the film or sensor plane, allowing the lens to focus significantly closer than its minimum focus distance. It is ideal for macro and close-up photography, such as capturing insects, flowers, or fine textures, without adding additional glass to the optical path.
