The Ricoh WG-4 offers a 16 megapixel sensor and a 25-100mm equivalent lens. Identical to its WG-4 GPS sibling in almost every way except for the obvious (one has GPS and a front-facing display, one doesn't) the WG-4 is waterproof to 14m/45 feet, coldproof to -10° C/14° F and shockproof to 2 m/6.6 feet. It's unique in its offering of six LED lights around the lens for use in macro shooting.
