The PowerShot G9 X is a camera that has been released by Canon alongside the G5 X camera. Indeed this particular offering uses the same 20.2-megapixel 1-inch-type sensor and DIGIC 6 image processor as the G5 X, meaning it also happens to have an ISO range of 125 to 12800, a maximum burst speed of 6 frames per second and the ability ot capture Full HD 1080p video at 60 frames per second.
However, this particular camera features a 28-84-mm equivalent F2-F4.9 setup meaning it is not able to zoom in as far as the G5 X. However, this is balanced out by the advantage of being more compact and lightweight than the G9 X.
Clearly, the PowerShot G9 X is a camera that is targeted towards those who value a lightweight and compact option.
