The Extension Tube EF 12 is installed between the prime lens and the camera
body. It is a simple way to enable close-ups at high magnifications by
increasing the distance between the lens and the film plane enabling focusing at
closer distances than otherwise possible.
This close-up accessory maintains full electronic coupling between the camera
body and lens and can be used with most EF lenses. Ideal for nature photography
with single focal length telephotos. Manual focusing is recommended.
