The Canon Extension Tube EF 12 II 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.
Extension tubes are one method of getting closer with EF lenses. A powerful tool when attached to standard and wide-angle lenses, they are also used with telephotos to get just a bit closer. With any lens, the longer the extension tube, the greater the close-up effect. The 12mm EF 12 II is often used with wide-angle lenses, while the longer EF 25 II is a better choice for normal or telephoto lenses. Auto exposure continues to work reliably, but manual focus is recommended in most instances. The version II extension tubes are also compatible with EF-S 18-55mm f/3.5-5.6.
