When in aperture priority mode does the camera take IBIS into account when selecting a shutter speed? (I have an om-d e-m10, but I suppose the question applies to Panasonic bodies with IBIS as well.) I'm thinking that it doesn't based on a quick test I did. In a somewhat dark scene I took two photos - one with IBIS on and one with IBIS off and the shutter and ISO remained the same. Would I need to manually select the shutter speed (S, P, or manual mode) to really get the IBIS benefit for helping get a proper exposure when the aperture isn't particularly fast?
