The Canon PowerShot G is a series of digital cameras released by Canon. The G series cameras are Canon's flagship compact models aimed at prosumer photography enthusiasts desiring more flexibility than a point-and-shoot without the bulk of a digital single-lens reflex camera.

The G series offers features such as the use of a lithium-ion battery, an articulated LCD screen (G7, G9, G10 and G15 have a fixed panel), Raw image format capture (all models except G7), a lens with a wider maximum aperture than standard PowerShot models, remote capture (except G11), and faster electronics. The range also includes a hot shoe for an external flashgun, including Canon's EX range.

Main specifications

G1 to G6

Common features across the early G series were:

• A fast lens (minimum F number of 2.0).
• A flip out and twist LCD, along with a smaller status LCD on the top of the camera.
• Raw image format capture.
• 1/1.8″ CCD sensor.
• Manual selection of aperture and shutter priority.
• Custom white balance.
• Built in flash.
• Hot-shoe for external flash.
• USB connectivity.
• A Compact Flash card slot.
• Availability of optional wide and teleconverter lenses.
• Canon’s proprietary EOS shooting modes, allowing the photographer to select different exposure settings for different environments.
• Included infrared remote control.
• In-built neutral density filter from the G3 onwards.
• Lithium ion battery.

G7 to G12

Canon Powershot G9

The G7 marked a major change in the G series. Previous G series models had featured a fast lens, Raw image format capture, and a tilt-and-swivel LCD. These were all considered hallmark features of the G series, but were removed or altered for the G7. Some of the major changes included:

• Introduction of a lens with a minimum F number of 2.8, compared to 2.0 in other G series cameras. Although slower, this lens introduced improvements such as optical image stabilisation, a higher zoom range (6×), and a macro mode that would focus as close as 1 cm. The lens would also retract completely into the camera.
• Change to a fixed LCD rather than a tilt-and-swivel model. The fixed LCD was larger (2.5″ versus 2.0″ on the G6) and increased the number of pixels by 75%. The tilt-and swivel LCD was restored with the G11, but removed again with the G15.
• Removal of RAW image format on G7, but returned for the G9–G15.
• No infrared remote control.
• Change from CompactFlash to SDHC card storage.
• Black, mostly metal, body.
• Canon G12 records videos up to 720p HD quality, G15 1080p HD and G1X 1080p. G15 and G1X do allow to use zoom and autofocus during video recording.

Many of the changes made allowed the G7 to be significantly slimmer than previous G series cameras (e.g., the thickness of the G7 is 4.25 cm while the G6 is 7.3 cm), making it more portable.

The decision to remove RAW shooting support was heavily criticized. DPReview stated that they were disappointed with the loss of RAW format,^[1] while Luminous Landscape stated that the removal of RAW meant that too many technical decisions had to be made while shooting instead of post-processing.^[2] RAW support can be enabled on the G7 using a free firmware add-on.

The G9 was released in 2007. Among its features were restored RAW support, a larger LCD screen, and a 1/1.7″ sensor rather than the 1/1.8″ sensor on previous models.^[3]

The G11, released in 2009, reintroduced the flip out and twist LCD (2.8″). It also features a lower resolution sensor than that of its predecessor, the G10, because the new CCD favoured low light performance over resolution.^[4]

G1X

The G1X was introduced in February 2012 and is a significant step out of the traditional G-line because of its much larger sensor, and it is the first model featuring a CMOS sensor. The G1X's sensor measures 18.7 x 14.0 mm (1.5"), which makes it even 16 percent bigger than the Micro Four Thirds standard, but still 20 percent smaller than APS-C Canon sensor. The camera is also bigger and heavier than the other G-series cameras, and the zoom range in equivalent 35mm is only 28-112mm (4x).^[5] With its aperture F2.8-5.8 and its sensor relatively slight smaller than Canon APS-C sensor, so the G1X camera-lens system can be comparabled with Canon EF-S 18-55mm f/3.5-5.6 IS II SLR Kit Lens on Crop format Canon DSLR which the G1X leads at wide angle and Canon EF-S will leads at long end zoom, but with shorter zoom than the G1X.

G15 and G16

The G15 marked a return of the G series lens to the fast lens faster than that of even early G cameras. Other features of the G15 include:

• Reintroduction of a fast lens (minimum F number of 1.8 and a maximum of 2.8; the G12 and G1 X had a minimum F number of 2.8)
• Pop-up flash button from the top of the camera
• Restoration to 5x optical zoom (the G1 X had reduced optical zoom to 4x).

The G16 shows only minor changes over the G15, for example:

• faster image processment
• full HD movies with 60 fps

Accessories

Canon Powershot G9 with custom accessories

The Powershot G series can accept a number of photographic accessories. Filters and other threaded lens accessories can be used with an adapter tube. Adapter tubes are available from Canon or third party suppliers. Most adapter tubes have 58 mm filter threads. In addition to standard filters and close-up lenses, the adapter tube can be used to attach wide angle or telephoto converter lenses to the Powershot G series. Starting from the G7, there is a bayonet mount on the front of the camera around the lens to directly attach lenses and accessories.

Powershot G series cameras have a standard threaded socket for mounting to a monopod or tripod. This can also be used for attaching the camera to various brackets or adapters.

With the hot-shoe for external flash, the Powershot G series can accept not only compatible flash units but also various connecting cords and wireless triggers. However, the Powershot G series is sensitive to the voltage produced by certain flash units, particularly older designs. Canon recommends that the maximum trigger voltage be less than 6 volts for any flash or accessory attached to the hot-shoe.

Flash compatibility is somewhat of an issue with the Powershot G series. Canon EX flashes are compatible but all EX features may not necessarily be usable. In particular, when the Powershot G is in manual exposure mode, the external flash is also in manual mode; that is, ETTL flash control is not operable.

Use by journalists

G series cameras have seen some use by photojournalists. John D McHugh used a G12 when covering the Bahraini uprising.^[16]
