Has anyone used face detection on the Fuji X-T1? I have noticed a strange behavior. After taking the shot, an automatic preview of the image comes up in the viewfinder and the preview then zooms to the area where the face is (that is, the detected face outlined by the rectangle). This process takes 2 to 3 seconds and the camera is unusable during this time. Does anyone have any advice on how to put this preview off? I shoot events and most often I cannot wait for 2 to 3 seconds between shots. Thanks for your help!
