Canon PowerShot G
From Wikipedia, the free encyclopedia
The Canon PowerShot Gx is a series of digital cameras released by Canon. The G series cameras, aimed at photography enthusiasts, falls in the middle range of Canon's digital camera offerings and are a step up from the mid-level A series.
The main physical differences from Canon's PowerShot A series includes a hot shoe for an external Canon EX flashgun, the use of a Lithium ion battery, a lens with a wider maximum aperture, a larger body with more controls, and until the introduction of the Canon PowerShot A80, a flip-out-and-twist LCD. Internally, the G series offered higher resolution and added more sophisticated electronics with features such as the Canon RAW image format, although Canon didn't offer the format on the PowerShot G7 nor did it offer a flip-out-and-twist LCD.
The G series is similar internally to the Canon PowerShot S series (not to be confused with the Digital ELPH S/SD series), with new S series cameras usually being introduced at the same time as similarly-specified G cameras.
There are six models in the series, the latest being the G7 in 2006:

[edit] Reasons for the exclusion of PowerShot G4
Canon, based in Japan, omitted the number 4 from the range due to cultural superstition.
- "The word "four" is read as "si" in Chinese Mandarin and "shi" in Japanese, a close homonym for the word for death in both languages and in the Cantonese dialect spoken in Hong Kong." [1]
Amateur Photographer also supported this:
- "the truth behind the leap from 3 to 5 is one based on cultural superstition — in Japan, the number 4 is considered unlucky. This is because the pronunciation of 4 — “shi” — is the same pronunciation as death. This is the reason why the EOS range jumps from the EOS 3 to EOS 5, and why the latest IXUS digital compacts bucks the trend of the IXUS v2 and IXUS v3 models by becoming the IXUS 400. Indeed, to find a Canon camera with a model number 4 you have to look back as far as the 1950s to the Canon IV." [2]
[edit] PowerShot G5
The G3 and the G5 were for a short time available simultaneously, although the older model was later discontinued. The camera also employs color filters that allow for noise reduction and better color saturation. The lens also allows for a wide range of apertures including a macro focusing mode.
This camera also uses a DIGIC Image Processor unit which allows the camera to process and shoot pictures at a faster speed — up to 3 frames per second. DIGIC improves the camera’s focus speed, exposure settings, and white balance.
Finally, the G5 also comes with a built-in flash with both manual and auto modes. The flash also has red-eye reduction and slow sync.
[edit] PowerShot G3 and G5
Apart from the other models that are totally different cameras - the G3 and G5 are in fact same model equipped with different sensor - featuring same lens, same body, same electronic and same functions in the software.
