The PowerShot G15 is a digital compact camera made by Canon from 2012. It has a 12.1-megapixel CMOS sensor (the camera offers a number of different picture formats, some of which do not use all of the sensor). It has a 6.1-30.5 mm f/1.8-2.8 zoom lens, a considerably wider aperture throughout the range than its predecessor (the G12; there is no G13 or G14); this is equivalent to a 28-140 mm zoom range on a 35 mm camera, the same range as the G10 and G12.

Like its predecessors, the G15 has an optical zoom viewfinder. It also has a 3-inch LCD rear display screen, with about 920,000 pixels; a little larger than that of the G12. Unlike its predecessor, this display does not tilt and swivel.

The arrangement of the main controls is different from the preceding PowerShot G-series cameras. On both the G10 and G12, the mode dial and one for ISO were concentric, on the right of the top plate, and exposure compensation was set with a third dial on the left. On the G15, ISO speed is set with menu controls on the rear of the camera, and the mode and compensation dials are stacked, the mode dial above and in front of the compensation dial.

Adjustment within a mode (i.e. shutter speed when in shutter-priority AE) are made a wheel on the top front shoulder, positioned for the shutter-release finger, allowing easy adjustments without removing the camera from the shooting position (this front dial was introduced on the G12).

Exposure times 1-1/4000 second are available in programmed exposure modes; in Tv (shutter-priority) mode, speeds 15-1/4000 second can be set. In manual exposure, time exposures up to 250 seconds can be set.

The lens aperture is continuously variable between the maximum for the focal length (f/1.8-f/2.8) to f/8 when in program modes or shutter-priority; when manually set, the aperture can be set in one-third stops.

Canon claim the camera has an improved autofocus program relative to the G12, and also faster reading of the image data from the sensor to storage.[1] It has an electronic level sensor, allowing the camera to be set level in both roll and pitch senses.[1]

Like most digital cameras, the G15 can also be used for video. It records 1980x1080 pixel video (a great deal more resolution than the G12) at 24 frames per second.

Like its predecessors, the camera has a hot shoe.
