I attended a 3rd birthday party for my nephew yesterday and decided to bring along the G7X to get some pics of the family (as opposed to my Olympus EM10). Overall was very impressed with the responsiveness of the camera. Setup a Custom Mode that automatically set the camera to Av mode, Aperture of 4.0, Flash set to ON (when it is popped up) and Face AiAF (which is not my normal Small Center Spot Only but seems better when basically taking pictures of faces). What surprised me is even with very good lighting in the room and using the flash, the camera was constantly choosing a much higher ISO - almost every flash shot was at 640 - than I would have expected. My EM10 and the Stylus 1 (that the G7X replaced) rarely selected an ISO higher than 200 when the flash was being used. BTW - I have the AUTO ISO flash setting set to STANDARD rate of change - but not sure what effect that would have had. Now I know that I could have used manual ISO - might consider this in the future - but still very surprised at how high an ISO the camera was selecting.
