Review: Fujifilm EF-X500 Flash (Fujifilm X Series)

The Fujifilm EF-X500 flash may be an option for photographers who want and need to use a flash when documenting and doing photojournalistic work; but it absolutely baffles me that a camera company with a fantastic medium format camera system hasn't started to work with some sort of third party lighting manufacturer like Profoto to get some sort of integration into their system.
