Sony has revealed two new 10.1-million-pixel cameras that are due to go on sale in the UK next month.

The Cyber-shot T77 is billed as the world?s slimmest camera with a 4x (Carl Zeiss) zoom and optical image stabilisation. Out in five ?fashion colours? the camera measures 13.9mm at its thinnest point and sports a 3in LCD touchscreen. This model will cost £248.99.

Features include face detection, ?anti-blink? technology and Intelligent Scene Recognition. A leather case will be available as an optional extra priced £35.

The Cyber-shot T700 boasts 4GB of on-board memory, and a 3.5in ?widescreen? with a 921,000 dot resolution.

A new ?Sharemark? function is designed to make it easier to upload images to photo sharing websites. While the ?Album? mode aims to help users organise their images by storing them in on-camera folders.

Bundled software allows full-sized images to be transferred to computer in a ?single click?. Smaller ?resized? files can then be moved back to the camera for ?mobile viewing?, says Sony.

The T700 is due to hit stores with a £299 pricetag.

Two underwater cases compatible with the cameras were also shown to journalists, at a press event in central London last night.

One is designed to be waterproof down to 40m (priced £189), while another is waterproof to depths of 1.5m and is expected to cost around £50. The prices of these accessories are yet to be confirmed. They are due out in October.
