Canon PowerShot G15 Quick Review
Compared to Canon Powershot G12 and G1 X
On this page we give you an overview of the design and operational differences between the Canon Powershot G15, its predecessor the G12, and both cameras' large sensor cousin, the G1 X.
Camera body comparison
When seeing the G15, G12 and G1 X side-by-side, at first it's hard to tell the three cameras apart. They share almost identical styling and ergonomics, and their dimensions are pretty close as well. However, upon closer examination the differences become quite obvious. The G15 is the smallest and lightest of the three, which makes it the best option if pocketability is far up your list of priorities. As you can see from the top-town view, the G15 is considerably slimmer than either the G12 and G1X.
The difference in dimensions compared to the G12 is largely caused by the lack of the swivel LCD, which makes the G15 about 17% slimmer. This margin is by no means massive, but it makes a difference when handling the camera and storing it in a coat pocket. The G1 X of course is a totally different kettle of fish. Although it closely follows the G-series design ethos, its much larger sensor (vs the G15 and G12's 1/1.7" sensor, see diagram at the bottom of this page) requires a much larger lens which protrudes from the body even with the camera switched off. This is also the reason why the G1 X is approximately 180 grams heavier than the G15, at 534 grams.
Key specification comparison
The table below compares the G15's key specification against its predecessor G12 and Canon's large-sensor compact, the G1 X. Compared to the G12 the G15 has a sensor with a slightly higher pixel count, sports the newer Digic 5 imaging processor, a faster lens, higher resolution screen, expanded ISO range (on the G12 ISO 6400 and ISO 12800 are only available in a very limited high sensitivity mode), faster continuous shooting and higher resolution video recording.

The G1 X's specification reads more similarly to the G15's, but the camera is larger and heavier due to its larger sensor (see diagram below). It also means that the image quality, especially at higher sensitivities, is considerably better than the G15, with more image detail and less noise. That said, the G15's faster lens means that you can select a lower ISO setting to achieve a certain shutter speed in a given light situation, reducing this particular advantage of the G1 X's larger sensor. The diagram below shows the size of the G15 and G12's sensor (1/1.7") in comparison to the G1 X's and other popular sensor formats.
|The Canon Powershot G15's 1/1.7" sensor is slightly larger than the 1/2.3" sensors found in most compact cameras, but significantly smaller than the 1" sensor that can be found in the Nikon 1 system cameras and the Sony RX100, or the 1.5" sensor of the G1 X.|
