Canon Extension Tube - EF 12 II

Description Boost Your Magnification The Extension Tube EF 12 is an easy way to boost your magnification when shooting close-ups. It simply fits between your prime lens and camera body, increasing the distance between the lens and the film plane, allowing you to focus at closer distances than you would normally be able to. 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.
