Canon EF 12 II Extension Tube

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.

The result of using extension tubes is that the distance from the back of the lens to the film surface is longer, which means you can take photographs at shorter distances to the subject. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits.

When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters).

This updated version II is now also fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses.

Extension Tube EF 12 II is recommended for lenses with a focal length of 50mm and up (EF-S 18-55mm can be used at middle and tele zoom settings).
