One of the advantages of the Fujifilm GFX system (GFX50R, GFX50S, GFX50S Mark II, GFX 100, GFX100S) is its highly customisable buttons which allow photographers to quickly and easily create shortcuts for important settings.

One such setting is the switching the Electronic Viewfinder (EVF) from Preview Exposure to White Balance Mode, which is essential when shooting with flash lighting as your main source of light.

The Preview Exposure mode is fairly self-explanatory, allowing the user to preview the camera settings (shutter speed, aperture, ISO) through the EVF.

The White Balance mode essentially forces the EVF to make compensations for shooting with flash by brightening the exposure of the EVF, allowing the user to see clearly see their subject matter through the EVF.

A quick way of setting a shortcut to switch between the Preview Exposure and White Balance modes is to:

1) Press and hold the DISP/BACK button down for a few seconds until the “Function Button” menu appears.

2) Cycle through the available buttons to which you can assign functions, but please note some of the buttons have a limited selection of functions you can assign to them. Our suggestion would be to assign the Preview Exposure / White Balance mode switch to the following button:

You can now use the designated button to switch between the Preview Exposure and White Balance modes. This same methodology can be used on the entire GFX range, allowing users to quickly and easily customise the buttons on their GFX cameras.
