The Pentax Optio W60 is a 10 Megapixel compact with a 5x optical zoom, 2.5in screen and a waterproof body which allows it to be fully submerged underwater without the need for an additional housing. Announced in May 2008, it’s the successor to the Optio W30 and upgrades almost every respect, including resolution, lens coverage, screen detail and the underwater specification.
The Optio W60 also boasts a superior underwater specification to its current arch rival, the Olympus 1050SW, with Pentax claiming a maximum depth of 4m for up to two hours compared to 3m for one hour for the 1050SW. To be fair though, you’re unlikely to notice the difference in practice. Few people will be underwater at shallow depths for this length of time, and even if they were, battery life would be a bigger problem, especially if the water was chilly. Read the whole review here.
