I'm ready to upgrade my point and shoot camera. I've got a 5 year old Nikon that's been pretty good, but I'm looking for a bit of upgrade. Ideally my budget is $500 or less, and it must fit comfortably in my pocket and have WiFi connectivity. Fast autofocus is a must, as I'm certainly a photo novice and will mostly use it in AF mode. We just had a baby and capturing her smiles is of utmost importance:) I've been doing a lot of research and three seem to keep coming up as well reviewed:

Sony RX100 (the newest IV is out of my price range unfortunately)
Canon G7X or G9X
Fuji XQ2

Anyone have any personal experience with these? Any others I should look into?

TIA!
