Introduction
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.
Advantages
- Version II extension tubes are the only
tubes compatible with EF−S 18−55mm lens
- White index mount is for EF−S lenses ; Red
dot is for use with EF and TS−E lenses
- EF 12 II Extension Tube is especially suited
for close−focusing with Wide−Angle lenses
- Extension tubes work well with telephotos to
allow closer focus than normally possible
- Manual focusing is recommended, and with
zoom lenses, focus after zooming is completed
