A: No, the Sensei PRO 40.5-52mm Aluminum Step-Up Ring will not fit the front thread of the Fujinon X30 camera because the front thread of the non interchangeable X30 lens is an unusual 40mm, not 40.5mm.

Q: 9. I have a Canon 24-70mm ef L lens f.2.8 uses 82mm filter. I want to step down to myCanon 24-105mm ef L lens with 77mm filter will this step down ring work?

A: It depends... If your camera has an APSC-size sensor, it will probably work. On a full-frame, it is very likely that you will end up with dark corners at the wide end, because at 24mm the lens has a wide view, and the step-down ring + the filter will extend too far forward and cause vignetting. Best way is to hold your filter about 3-4mm in front of the lens and see if it does cause vignetting.
