As I perused another website, someone seemed to assert that with the gx85 this was possible. In the camera itself, I don't see this option. Maybe I'm not looking in the right place? What I would like to be able to do is set the aperture and shutter speed while the camera chooses the iso value. My old Pentax k3 had this feature. Is this something that's possible on any Oly or Panny cameras? If so, which? Also, how do you enable this feature?
