100mm L and kenko tubes

[thewiz4u]

Well, I just got my macro lens 5 days ago and cant get enough of it so I'll like to get closer to the action. What kenko tubes do I need to get? I'm working with a 5D2 and a 1D3. Thanks guys, what a pleasure for me is be part of this board, you guys keep photography interesting, innovative and captivating.:D

Kenko makes a set of tubes that work with only EF mount lenses and a set that works with both EF and EF-S. Since the 100mm L is a EF mount lense, either set will work fine.
Note: The EF only tubes will say "C/AF" and the EF-S tubes will say "C/AFs"

Fixed Typo

Note: The EF only tubes will say "C/AFs" and the EF-S tubes will say "C/AFs"something is wrong there :P

I noticed it too. No change is how the tube sets are identified. The OP will probably correct the typo.

I fixed my ealier typo and I have some pictures of the extension tubes in this thread so you can see what the distinction is. http://photography-on-the.net/forum/showthread.php?t=793256
