The EX-Z500 is a very slim and compact camera, similar in overall style to Pentax's Optio S range. Previous Casio compacts had made use of Pentax's innovative Sliding Lens System, allowing them to be among the slimmest digital cameras on the market, but the Z500 appears to have a completely new lens. It is similar in design and appearance to the Pentax system, but it is physically smaller, giving the camera a thickness of just 20.5mm.
