Q: 10. Will this fit a Fuji X30?

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. The FUJIFILM X20 Lens Hood and Filter Set for X10, X20, or X30 Camera: https://bhpho.to/2WTA0sh features a step up ring 40mm to 52mm. It is the only step up ring that will fit the front thread of the Fujinon X30 lens.
