There are a couple of settings which have always been critical to the Fuji AF operating correctly which are not default. I’ve seen some comments regarding poor performance and IBIS but I’ve also seen plenty of positive comments and excellent photographs. Faulty IBIS is quite easy to check of course, just turn it off
, checking AF is more difficult of course.
If I had doubts I’d be back at the retailer. I’m surprised how different it feels to my previous XT cameras but any issues I’ve had I’m pretty sure are down to user error and I’ve been able to identify why.
