Zed Pro Media has made a review video on the Fringer EF-FX Pro. Unfortunately they took it down due to the controversial shooting environment, i.e. on railway tracks. Although I don't support shooting a video on railway tracks in use due to safety concerns, I do like the content of that video. It's a pity. However, I found before it's taken down on Youtube, someone has already mirrored it on another online video platform. Try this: Adapting Canon Lenses to Fujifilm X-H1
