The Pentax Optio T20 from the outside looks like any ordinary compact camera. Small and compact, the camera is just 19.5-mm thick, there is your standard 3x optical zoom, and a large LCD display on the back. However its not until you look closer that you realise that the camera is void of buttons. Yes there is the shutter and zoom buttons on the top, but the back sports just a menu and playback. Where are all those buttons you ask, well, and here is the clever bit, Pentax has opted for a large 3-inch LCD touchscreen that gives enough room for big fingers to touch the on-screen menu.
