Like a lot of Canon's higher-end compact PowerShots, from the S120 up, the G7 X has a multifunction ring on the lens.
Ironically, the lens is the fastest in the G X series; only the G16 has a comparably fast one, albeit at a slightly longer zoom range.
No hot shoe
Canon really is mimicking Sony; the only other camera in the expensive end of this class that lacks a hot shoe is the RX100 II and like that camera it lacks a grip.
The G7 X takes the offset double dials of the G16 -- exposure compensation and mode -- and stacks them.
The back control layout is roughly the same as the G1 X Mark II. One significant difference is the dedicated button on the back for programming the function of the lens ring.
Yes, it does selfies
Like every other camera coming out these days, the screen flips up for photographing one's own face.
The camera has a dedicated button for initiating a Wi-Fi connection for devices that don't support NFC -- i.e., pre-iPhone 6-generation iPhones.
Like most of the cameras in its class, the G7 X has a micro HDMI and USB connections.
Although it doesn't use the NFC logo for some reason, the wireless icon is where you tap to automatically launch the connection and the mobile app.
