Continuing the rugged heritage of the WG series of cameras, the Ricoh WG-4 is waterproof to 45 feet, shockproof from drops of up to 6.6 feet, cold proof to 14 degrees Fahrenheit and crushproof, withstanding up to 220 foot-pounds of force. In addition, the Ricoh WG-4 features a 16-megapixel CMOS sensor and a thoughtfully designed folded optical 4X zoom lens, enabling its pocketability while also ensuring its optics are not exposed dust and moisture like those of a protruding lens barrel.
