Casio is about to launch what it claims is the world's thinnest digital still camera equipped with a monitor.

The Exilim comes in two models, the EX-S1 and the EX-M1. The EX-S1 is 88mm wide and 55mm high (the size of a credit card) and 11.3mm thick. The EX-M1 is the same width and height but 12.4mm thick. They weight 85g and 87g, respectively.

Both cameras can record 1.2Mp (megapixel) still images and 30 seconds of 320x240 pixel moving images and replays. The EX-M1 also features an MP3 audio replay function and can record 50 minutes of speech on its 12MB of internal Flash memory. This is a paltry amount of space, so you're probably best off with the dedicated, slimmer camera-only unit.

Both products have a 4x digital zoom lens, a slot for either a Secure Digital card or MultiMedia Card and a 1.6in colour TFT (thin film transistor) monitor. The battery should allow around 480 still images to be recorded. The Exilim will be rolled out in Japan from the end of June, with a simultaneous European release expected.

The EX-M1’s battery should let users record an hour and 20 minutes of speech and play five and a half hours’ worth of MP3 tracks, according a Casio press statement.

Expect to pay around £190 for the EX-S1, £250 for the EX-M1.
