I posted a question on the other Fuji forum I use about why my EX-20 flash wasn’t firing and learned (not mentioned in either the X Pro 2 or flash manual) that one must use the mechanical shutter. Don’t know why, but OK. One reply went on at great length on why to never use the electronic shutter except when silence is needed. I don’t believe that Fuji would put it in there for only that reason. May I ask for some thoughts on the electronic versus mechanical shutter decision? Thank you.
