Ricoh PXRicoh has today unveiled the PX, the first in a new series of digital compact cameras designed to be both water and shock resistant.

Ricoh claims that the 16-million-pixel PX can be used at an underwater depth of 3m, for up to one hour, and withstand drops from a height of 1.5m.

Powered by a rechargeable battery, the PX sports a 5x optical lens designed to deliver the 35mm viewing angle equivalent of a 28-140mm zoom.

A digital zoom expands zoom power to an equivalent focal length of 1,344mm, adds Ricoh.

Features also include a 2.7in display, subject tracking AF, a Smooth Imaging Engine IV processor and an HD (1280×720 pixels) video function.

Minaturize, Toy Camera and Soft Focus are among the PX?s digital filter effect options.

The PX is compatible with the X2-series of Eye-Fi SD memory cards and will go on sale in the UK next month, priced £179.99.
