Conclusion: There's no doubt that the Pentax Optio WG-3 GPS is designed for underwater use, as it's Pentax's 15th-generation waterproof model. Don't be fooled by its quirky design or bright colors; it is a serious, rugged camera, full of features, and capable of taking great underwater photos.

Pros: Robust and well waterproofed, The presence of GPS, Altimeter and barometer, Relatively bright zoom lens.
Cons: Only decent image quality, Autofocus is not very powerful, Not very intuitive menu. Extreme design is not for everyone.
Summary: The Pentax WG-3 offers a curvy, rugged design that can handle tough conditions with aplomb. Its lens is noticeably faster than most of its peers at its wide end, which allows for better low light photos. Its unique macro ring light and stand allow for extreme close-ups.
Summary: The Pentax WG-3 survived all our testing challenges and produced good levels of detail that rival the very best tough compacts in the market. Unfortunately, the WG-3 weakness is its performance underwater and it’s not uncommon to end up lightening images in software to create the best results.
Pros: Rubberised body; Attractive styling; Good image quality
Cons: Dark underwater performance; Screen scratches very easily; Slow zoom
Excerpt: Having recently tried other digitalcameras designed for those who photograph underwater I did not expect too many surprises from the PentaxWG-3. Here in the introduction I can say that I was wrong, very wrong, as it has two features I have never seen before.
Summary: The WG-3 is the 15th generation of Pentax's ruggedized camera range, and it certainly shows. This is a solid product in more ways than one, both in terms of its build quality, ability to withstand most things that you could subject it to, and all-round handling and feature-set.
