Are you sure the Kenko tubes you got are for EF-S lenses? I have the EF-S 60mm F/2.8 and it doesn't attach to my Kenko tubes, I believe they are only for EF mount. I hope you didn't have your heart set on that. But I like my set of tubes. I use them with my Sigma 150mm when corals are closer than the lenses minimum focusing distance to go beyond 1:1 magnification. You do loose light so a tripod/shutter release is a must when using them.
