I shoot a lot indoors with the xt4 using flashes. The preview exp/wb is set to off so that the image in the evf wont be too dark.[My exp settings are set for the flashes and not the ambient light] However I often get a much too bright "whiteout" type of effect- so bright that I can hardly see the subjects untill I leave the shutter button and press it again. Anybody had this problem? I"m ready to sell the camera partly because of this.
