With summer fast on the approach - finally, and we sure do hope it's better than 2012 was - Sony has unveiled its latest waterproof, beach-ready compact camera, the Cyber-shot TX30.

The update to the long-dead TX20, the TX30 seems - based on the official press image - to reintroduce the slide-to-power-up design concept that we thought the newer TF1 model had all but brought an end to. With sliding parts any sand and water can get trapped and - crunch - it doesn't help the camera all that much.

Still, the TX30 has plenty of high points to shout about. It has a 5x optical zoom and is waterproof to a depth of 10m - which, according to Sony, is makes this the world's slimmest compact camera capable of such a feat. Sony sure does get the style down pretty much every time.

New to the series is on-board LED lights to light up dimmer underwater scenes, much like the Pentax WG-series of cameras.

The TX30 is built around an 18.2-megapixel Exmor R CMOS sensor and will be on sale come April 2013, just ahead of the summer sun.
