Canon Auto Focus Extension Tube EF 25 II for Close-Up and Macro Photography
Description
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.
