The Optio W10 sets the PENTAX standard for waterproof digital with 6.0 megapixels and a reflection-free LCD that offers optimal viewing in outdoor settings. This little beauty features JIS Class 8 waterproof and JIS Class 5 dustproof ratings.

"The Optio W10’s unique benefits are its waterproofing, its simplicity and its styling. Its image quality is by no means outstanding. Still, there will be plenty of people who want a convenient, moderately-priced beach camera or even a snorkeling camera, and they will be pleased with the W10. For under $300, the 6-megapixel, 3x optical zoom Optio W10 offers a unique feature set at its price point, although users will have accept the sacrifice in image quality for the added durability and underwater functionality."
