Does anyone know if there's some rhyme or reason to the compact camera names, such as SXxxx (with and without an HS suffix) or Axxxx or Sxx? Different target markets? Different key features? Or is it just a bunch of random letters?
A series: "Easy and Fun" budget cameras ranging from point-and-shoot to prosumer cameras
D series: waterproof, freeze- and shock-resistant
E series: design-oriented budget cameras
G series: flagship cameras with advanced features
S/SD series (also known as PowerShot Digital ELPH, Digital IXUS and IXY Digital): "Performance and Style" ultracompact point-and-shoot cameras
S/SX series: ultra-zoom cameras
S series: originally a series of compact point-and-shoot cameras, currently a series of prosumer cameras slotting beneath the G series
