Canon EF 12mm Extension Tube

Canon Auto Focus Extension Tube EF 12 II for close-up and macro photography.

Two Extension tubes, in the same 12mm and 25mm lengths as previously available, have been redesigned to accommodate the EF-S mount lenses and its extended rear elements. They're perfectly compatible with all previous EF and TS-E lenses, and will work with any EOS film or Digital SLR. Note that exposure compensation is often required with cameras other than the EOS-1 Series.

Kenko Extension Tube Set

Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.

The KENKO DG AUTO EXTENSION TUBE SET contains three tubes of different length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any combination to obtain the desired magnification. Kenko also makes a DG UNITUBE 12 mm or 25 mm which can be purchased individually.

Kenko's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Canon, Nikon, and Minolta lenses.

Olympus EX 25mm Extension Tube

The Olympus EX-25mm Macro Extension Tube can be coupled with lenses like the 50mm f2.0 Macro or 300mm f2.8 to allow a greater range of magnification for close-up photographs.
