From 1990-2005, Pentax sorted its compact cameras into two main groups. The low end range had a PC prefix, but the high end series was branded as Espio (IQZoom in the US). These were mostly quite advanced compacts with built-in flash, autofocus, and zoom lenses. Espio/IQZoom models are listed below.

Among Japanese compact camera producers, Pentax was a pioneer in actively relocating its production to oversea facilities, presumably to save labor cost. Only top-of-the-line models in this series were produced in Japan (e.g. Espio 160/200) while most models were assembled in Philippines or China.
