If you want an idea of the magnification, this is uncropped. The lines are the mm scale on a measuring tape.
This is with a minimum focus distance of 4 inches.

My Kenko extension tubes only have red dots, but they worked perfectly well on my 30D.

The question is with regards to the lenses not Bodies. (EF-S lenses protrude a little further into the mount area) Which is why EF-S lenses won't work on 1D's and 5D's as the EF-S lens could cause damage to the mirror. However there is an updated version of the Extension tubes made by Kenko that works with EF-S lenses. no modifications are need to enable the tubes to accept EF-S lenses it is a compatibility issue with the lenses not camera bodies. Apologies if I misunderstood. I've only ever used the tubes with EF mounted lenses.
