Why no PowerShot G4?

Canon, based in Japan, omitted the number 4 from the range due to cultural superstition. 4 (four) is a number, numeral, and glyph. ... A superstition is an irrational or invalid belief about the relation between certain actions (often behaviors) and other actions that is not true, such as fear of the number 13. ...

"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: A homonym is one of a group of two or more words that have the same phonetic form (i. ... Standard Cantonese is a variant of Cantonese and is generally considered the prestige dialect of Cantonese. ... Amateur Photographer is the title of a British photography magazine, published weekly. ...

"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]

The Canon EOS (Electro-Optical System) autofocus 35mm film and digital SLR camera system was introduced in 1987 with the Canon EOS 650 and is still in production as Canons current SLR system. ...

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. In optics, an aperture is something which restricts the diameter of the light path through one plane in an optical system. ... Colony of aphids on a stem. ...


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.

Canon Powershot G2 (5979 words)
Canon Powershot G2 by Zlatko Batistich and Patrick-Michel Dagenais, Nov, 2001
I think it's safe to say that the Powershot G2 tries to be two things at once - a camera for the casual digital photographer that is weary of image quality, and the more seasoned photographer who's had enough of his limiting point and shoot camera and now needs more control over what he's shooting.
Canon should be encouraged to pursue this direction.
