I just bought the G7, and so far it's been good. The camera feels faster than the E-M5 when it comes to menu, turning it on, etc. The only thing that bugs me is not having IBIS. The camera chooses a high ISO instead of a slower shutter speed. Is there a way I can let the camera choose a slower shutter speed? I think the LX100 did that. Do I have to stay in shutter speed mode?
