Specifically, I'm referring to the issue with the X-T2 where the batteries in the grip intermittently display as fully depleted when they're not. Lots of people are having this problem (including me). See link below for a thread on this forum on the issue with the X-T2 battery grip.
I'm hoping others who have the X-T3 can share whether they're seeing this issue or not. Even though the camera is new, anyone using the grip regularly will know whether or not this defect is still there. I bought my X-T2 and battery grip two years ago and it exhibited this behavior from the outset.
