Canon Extension Tube EF 12 II

The application of extension tubes results in an increased distance from the rear of the lens to the film surface, allowing for photography at closer ranges to the subject. Consequently, extension tubes are frequently utilized in macro photography and occasionally for close-up portraiture. When employing the camera's TTL metering system, there is no need for exposure compensation, unlike when using handheld meters.

The revised version II is now fully compatible with Canon Digital EF-S lenses, in addition to standard EF and TS-E lenses.

The Extension Tube EF 12 II is particularly effective for close-focusing with wide-angle lenses. It is compatible with all lenses, with the exception of the 15mm f/2.8 fisheye, 14mm f/2.8L, and MP-E 65mm f/2.8.
