Today we have posted not one, not two but three full in-depth reviews of three ultra-compact three megapixel digital cameras. Reviews posted today are of the Pentax Optio S (3 mp, 3x), the Casio EXILIM EX-Z3 (3 mp, 3x) and the new Canon PowerShot SD100 (3 mp, 2x). All of these cameras are aimed as pocketable 'carry anywhere' cameras with a basic easy to use capability as well as a few advanced features you can grow into. Each has their merits but which offers the best combination of image quality, feature set and value for money?
