Pentax is a camera maker with a long tradition in the film-based world, but is one of the newer entrants in the digital arena. After co-developing several cameras with Hewlett Packard, they stepped out on their own a couple of years ago with digicams entirely of their own design. The introduction of their "Optio" line of compact digicams offered sleek, ultra-compact body styles with ample features, perfect for anyone on the go.
