Canon PowerShot G5 X Review

One of the expectations of consumer electronics is that over time, you will get more power for less price. That is certainly true for computers, but there isn't a "Moore's Law" for cameras. If you want a better sensor, then you have to pay more money.

The problem is that people don't necessarily want a better sensor camera, but if they want a camera, it has to be better than their cell phones, which have also been getting better nonetheless. And so, the 1/1" sensor format, which was once considered "large" and premium, is now pretty much the mainstream standard for compact cameras. The 1/1.7" format, which was once the largest format for premium compacts, is now defunct, and so is the premium positioning for cameras built around this format. To that end, the venerable Canon S120 and G16 are now gone, replaced by the G9X and G5X respectively. Of the two, the G5X is the more appealing to enthusiasts. Whereas the G7X is obviously derivative of the Sony RX100 cameras, the G5X is a more unique design... at least for Canon. The overall design could easily have come from Nikon's V3 team, and the pronounced flash/hotshoe/EVF hump is reminiscent of Fujifilm bridge cameras of years past.
