It fits exactly. The width is crucial, so with 100mm width it fits.

Q
Can i use this on a canon d80 100 mm macro ef lens ? it says 67 mm on the lens cap but i don't see the exact answer. thank you
A
67mm should also be stenciled on the front edge of the lens somewhere. If so, then you should be good to go. It should be on the lens because a lens cap can be lost or broken.
