Well, I don't understand why, but that works. I can see why it would be hard on the battery. I guess I could keep it on continuous but turned off on the lens, but that could get old. I also have a Fuji XT-2. I just checked and it is set on continuous and works just like the XT-30. I never noticed any undue wear on the battery. I don't understand the reasoning behind this, but it must be the way they intended it to work. At any rate, thank you very much for your help. Maybe I should read through the manual again!
