A lot of hints concerning the Fuji X Cameras can be found in this and other forums. Some are given as answers to questions others are posted as results of just exploring the cameras. Not everything is printed in the manual or is at least not to be found there easily. On the other side, these hints are not quickly accessible since they are hidden inside (long) threads.
Beginning now, we will pick up hints from different sources and place them in this special thread which will be complemented from time to time.
We are sure this will help everyone using their Fuji X cameras. Please leave us feedback or additional hints to add to our collection. Thanks to everyone who gave these hints in threads of our forum.
As far as possible, these hints are verified using an X-T2 or an X100F.
AFL Button not working
If the AFL (Autofokus Lock) Button does not show any response it is most likely due to active face recognition. Disable face recognition and AF-L will work again.
Shutter not working with adapted lens
Inside the menu there is a setting SHOOT WITHOUT LENS. Turn it on to shoot with an adapted lens.
Flash not working
Most likely the electronic shutter has been activated. Only the mechanical shutter supports flashing. Go to the menu setting SHUTTER TYPE and select MS or MS+ES (on some models it might be necessary to select MS).
Can’t select ISO100
Another issue when using the electronic shutter, ISO setting starts with 200. Use the mechanical shutter for ISO100.
Generally, it is not recommended to use ISO100, since the sensor is designed for ISO200 (I will spare you the technical details). Rather dim the light reaching the sensor by using the ND filter wich is implemented on many models, or use an attachable ND filter.
Bands in the photo or fringed edges on moving targets The electronic shutter is responsible here, too. Using it can result in interferences with some light sources and give you banding in your photos. The banding is not necessarily visible in the viewfinder or on the display. Rather use the mechanical shutter when shooting with artificial light.
Another issue of the electronic shutter is called „rolling shutter effect“. To put it simple, it takes too long to read out the complete sensor while objects are moving fast. Again, use the mechanical shutter with fast moving objects, e.g. when doing sports photography. If you need to dim the light reaching the sensor to go get slower (mechanical) shutter speeds use attachable ND filters and/or the built in ND filter.
Autofocus not working anymore
If the little red box resists to become green even though there is definitely enough light for the autofocus system, there are two possibilities:
The little switch on the front (on the side of the X100) is set to M (manual focus). Switch it to S or C.
The lens stopped working properly (autofocus function crashed somehow). Put the little switch to M and back so S or C and most likely the lens will work properly again. Alternatively, switch the camera off and on, but this will take more time than the first procedure.
Locking D-Pad and Q button Press and hold the MENU/OK button until a lock symbol and ON appear. This locks the D-Pad and the Q button. All other buttons are still operational, even the D-Pad works when you go the the menu.
To reactivate D-Pad and Q button press and hold MENU/OK again until the lock symbol and OFF appear.
If you own an X-H1 you can configure the buttons which will be locked using LOCK SETTING inside the menu.
Deactivating the annoying Q-Button
On some models the Q button is placed quite adversely so you might press it accidentally. Just deactivate it using the procedure described above (lock cursor buttons and Q button).
Until now only with the X-H1, you can disable just the Q button with the LOCK SETTING.
The viewfinder is not working / the display is not working
Most likely you pushed the button VIEW MODE. It’s quite easy doing so accidentally on some models. This results in changing the default behaviour, which is switching between viewfinder and display automatically (using an eye sensor next to the viewfinder).
So, if the viewfinder or the display seems not to be working tip the button VIEW MODE until an eye symbol and SENSOR appear on the display or viewfinder, respectively. And be careful not to trigger the eye sensor with your hand during this procedure (as a left handed person, this happens to me all the time).
The camera appears to be dead
If your camera doesn’t do anything after switching it on and the battery is definitely charged you may have loaded a defective or incompatible SD card. Unload the card(s) and try to switch the camera on. If the camera is working now servicing is most likely not necessary, just use another card.
Another option is to remove the battery and wait for about half a minute before putting it back in. Try without inserted SD-Card first. If it works the camera just needed a kind of reset, like other computers do 😉
Dead or stuck pixels If the viewfinder or the display (or the resulting photos) show some dead (black) or stuck (coloured) pixels, they should be gone after a while since the camera is doing a pixel remapping by itself from time to time. You can also start the remapping process from the menu on recent models. If the stuck or dead pixels resist this process servicing is needed. However, not all models do support pixel remapping.
Indicator lamp blinks green and orange after shot
Probably you have IMAGE DISPLAY set to Continuous. Change the setting in the Menu under SCREEN SETTING.
