Of course the x100f isn't designed for sports or action. However, it is a great people/moment camera. If you like to be handicapped into an intentional "slow down/calm down" more power to you. Me, I would rather have a capable and performing camera that snaps the shots when the moment happens. When I'm photographing kids running on the beach and jumping, it's nice to have close to the afs capabilities of the X-T2. We all use the tools we need. I need a performing camera. I can slow down with the x100f too, but I can't go fast with the x100 or my old x100s. The x100f gives me much more options of capturing images than the x100s so if there is a perceived difference in image aesthetics doesn't much matter if the camera can't get the shot anyway. I'm not a pixel peeper so I haven't seen a perceived difference anyway.
