Pentax has today announced its first swivel lens compact in the shape of the stylish Optio X which echoes Nikon's early design of the 900 series. The right hand side rotates 180 degrees upwards and 90 degrees downwards. Manfactured from aluminium alloy and resin coating, the Optio X boasts five megapixels and is the slimmest camera in the range at 18mm. It will be available in October.
