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 and G10 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. [1] The range also includes a hot shoe for an external flashgun, including Canon's EX range.

G1 to G6

Common features across the early G series were:

G7 to G12

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:

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,[7] 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.[12] RAW support can be enabled on the G7 using a free firmware add-on.[13]

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,.[14]

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.[15] It has been suggested that the G10 is better if you don't frequently shoot photos over 200 ISO, or require a flip-out screen.[16]

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 2011 Bahraini uprising.[17]
