Hey! You should know that Canon has released a newer version of this product: the Canon PowerShot G7 X Mark II.
Canon's first compact camera to feature a one-inch sensor is the Canon PowerShot G7 X. Announced in September 2014, the G7 X is a smaller, pared down version of the G1X Mark II that competes directly with the similar Sony RX100 II.
The Canon PowerShot G7 X is clearly an advanced compact with a one-inch sensor, bright f1.8 lens, manual modes and RAW capability, but it also aims to attract the selfie-lovers with a touchscreen that tilts 180 degrees and, of course, wi-fi. Those features are in lieu of the hot shoe slot on the more advanced G1X Mark II, but it also means it's not nearly as bulky. That same G1X also has a bigger 1.5-inch sensor, but the choice between the two isn't quite that easy, since the G7 X has a faster burst speed, a better video frame rate and a more updated process (that will likely mean better autofocus too). It likely comes down to deciding what is more important: easy selfies or a better resolution and the ability to add on an extra flash.
The highlight here is that big sensor and fast lens in a body that's not much bigger than a typical point-and-shoot--not to mention RAW capability and manual modes. The whole thing weighs just over ten ounces and is quite compact.
The Canon PowerShot G7 X is actually quite similar to the Sony RX100 II, especially on the exterior with the compact size and tilting LCD screen. They have a few differences though, mainly the RX100 II's faster burst speed (10 fps, though with fixed exposure) and hot shoe slot. The Canon has a bit better lens, with a slightly better zoom and a wider aperture at the end of that zoom range. The G7 X also has a few more focus points. Sony's RX100 II has a significantly better battery life, however; plus, since it's older, it's common to find it for at least $50 less.
Canon's G7 X is a good addition to their line--it's smaller and more affordable than their G1X Mark II, and offers features that appeal more to selfie-lovers. The competition is tight though, so be sure to check out the other similar options and choose which will fit your typical shooting needs a little better.
