As I reported some days ago I had a serious problem with my new X100F. The AF switch was broken and the camera could not be set to AF-S via the switch on the left side. The camera is now repaired and works fine again.
There is only one minor thing that bothers me a bit. Back in the days Fuji pulled my camera via UPS for free and now you have to send the camera in on your own bill (except you are a pro how owns more than two cameras). I think that this is okay if your camera is older than two years, but my camera was freshly bought and near mint. The guy I phoned with at Fuji repair was not really cooperative and I had to add another amount of money (delivery with insurance) to the pile of money I've spent on the camera. Sad but true.
I don't think that this is the right way to treat customers who bought a premium product.
UPDATE 17/05/12: My camera has a new problem now. The silver cell that keeps the settings when you change the battery is now dead. After one to three seconds the camera does a factory reset. The Fuji service staff told me that the circuit that was changed also contains that cell. So I have to send the camera again to the Fuji service. But this time they sent me a pull label via UPS. I hope this is the last problem with my brand new X100F...
