The Canon EF12 II close-up accessory maintains full electronic coupling between the camera body and lens, often providing greater magnification than is possible with close-up lenses. The Canon EF12 II Extension Tube can be used with most EF lenses, and are ideal for nature photography with single focal length telephotos.

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. The Extension Tube EF 12 II is especially suited for close-focusing with wide-angle lenses.
