I've been getting annoyed at the shutter speed decisions my GX7 is making. It is almost as if the camera just uses the same exposure logic as any other Panasonic without IBIS. For example, I have my 75mm prime on the camera, shooting indoors and auto ISO, and it still picks 2x EFL as if it had no stabilization. I know I can get at least 2 stops, if not 3. But it picks 1/160 no matter what the light is. The only way I can get it to actually use shutter speeds that make use of IBIS is if I use manual or shutter priority. Is there a setting I'm missing, or is it just the way the exposure program works?
