Some manufacturers claims to be pocket-sized often stretch the imagination - and the material. Pentax describes the Optio S10 as being 'ultra compact' but this time it's perfectly right. This camera isn't just pocket-sized, or even palm-sized – its tiny, it could even be called diddy.

Soon to complemented by the newest addition to Optio range - the S12, the Pentax Optio S10 Digital Camera measures just 87 x 54 x 21mm in size and weighs a mind-blowing 130g with battery and memory card in place.

One of the world's smallest 10Mp cameras - and probably the world's easiest to use - the Pentax Optio S10 is an absolute diamond of a camera that boasts an ultra compact body which simply oozes style. The Pentax Optio S10 is slightly heavier than some close rivals, but this makes it feel more solid and durable, adding to an already outstanding build quality.
