The Canon G9 X is the sleeker, lighter sibling to the G5 X. While it doesn't list quite as many features, it's also nearly half the weight and $300 less than the G5 X, introduced at the same time.
Like the G5 X, the Canon G9 X sports a large 1” sensor. In front of that is a f/2.0-4.9 lens—which is the biggest difference you'll see compared to the G5 X in terms of image quality. While very similar without zoom, at the end of the zoom, the G9 X has a much narrower aperture, which means the G5 X will be the better low light performer. Still, the lens specs don't look too bad for the lower price point, and there's a 3x optical zoom plus stabilization.
Canon's latest announcements haven't been too spectacular in terms of speed. The G9 X hits burst speeds of 4.3 fps (or 6 fps with autofocus locked on the first frame). That's certainly not the best speed in the category, but we're a bit more willing to settle since the G9 X also has a much lower price tag compared to the G5 X.
The G9 X doesn't have the G5's viewfinder, but it also comes in at nearly half the weight with a much sleeker, simpler design. Sporting a retro look with a faux leather wrap that's not characteristic of Canon, the camera is smooth and sleek, and pretty compact considering all the imaging power that's packed inside. There are fewer protrusions on the G9, with the exception of the control ring around the lens that we're glad to see stick around. The screen doesn't tilt, but it is a touchscreen.
The G9 X doesn't have the tilting screen or electronic viewfinder or bright lens of the G5 X, but it sits at a much more affordable price, and still includes features like a large 1” sensor, manual modes and RAW shooting. It's a good camera for enthusiasts that want an inexpensive camera that travels easier than their DSLR, or even consumers that want more resolution and power than you can eek out of a typical point-and-shoot. The $529 price point makes the absence of those features less of an issue.
The Canon PowerShot G9 X is available beginning October 23, 2015.
