The Pentax Optio Z10 is a small, compact digital camera with a twist - despite being the same size as a pack of playing cards, it features a 7x optical zoom lens equivalent to 38-266mm. Furthermore the lens is internal and doesn't extend from the camera, protected by a plastic screen and a sliding lens cover. The Pentax Z10 has an 8 megapixel sensor, digital shake reduction mode for both still pictures and video, a 2.5 inch LCD monitor, ISO 64-3200 and Face Recognition. A 7x zoom camera is something of a departure from the norm for Pentax, who usually specialise in more conservative 3x zoom models. Have they bitten off more than they can chew with the Z10?
