For what a fool I made of myself, you guys have been great. I'm glad I made the mistake because I never will again.
I'm still confused as to why Canon and other companies don't print onto the lens the actual focal length that will be utilized. I now know that the 18-135mm lens is an 18-135mm lens, but the camera and pictures being produced are not at 18-135mm, its at 29-216mm. Isn't it more "honest" and more relevant to tell the customer what the "actual" focal length(s) the lens will be giving him? Because zoomed out, its not showing 18mm, its showing 29mm. Telling me that it is 29-216mm lens would make more sense because that is what focal lengths are actually being used.
being confused doesn't make one a fool
For a ef-s (aps-c only) lens it doesn't make much sense to call a 29-216 lens a 18-135 lens because that lens will never be put on a FF body.
but then the confusion starts when you put a 24-105L (FF) lens on a crop body eq 38-168mm.
The numbers on the lenses are correct you just have to multiply it by the crop factor. FF=1x aps-h=1,3x and aps-c=1,6x
