真的嗎?dp說不能加減ev 是因為fw更新了嗎? Auto ISO is available in manual exposure mode, but the camera won't let you use exposure comp to specify how bright the image should be. Auto ISO is only available for video when shooting in P, A or S modes (so there's no way of setting your shutter speed and aperture, then getting the camera to maintain brightness). https://m.dpreview.com/reviews/panasonic-lumix-dmc-gx85-gx80/6
