Neither rain, nor sleet, nor snow, nor sand, nor mud, nor dust will stop the 6-megapixel Pentax Optio W10. This postal-worker-worthy camera is specially sealed to prevent damage from the elements, completely submersible in water to a depth of 1.5m for up to 30 minutes, and impenetrable to dust particles as fine as talcum powder. Even if you don't plan on taking it into the drink or the desert, the Optio W10's design makes it virtually immune to the wet, nasty weather that could kill other cameras.

Design

	The Pentax Optio W10's control layout is logical and convenient, despite the awkwardly recessed power button on the top edge.

The Pentax Optio W10's compact plastic body weighs about 156g, and at less than an inch thick, it can slip easily into your pocket; the modest 3x, 38mm-to-114mm lens zooms entirely into the body. It lacks an optical viewfinder, so you'll have to depend on its large, 2.5-inch LCD for composing your shots. The somewhat dim display is great for underwater shooting but can be difficult to view in low light. The screen barely gains up, and the LCD-brighten feature doesn't help much.

The camera's body feels relatively comfortable to hold, and it even has a space on the back to rest your thumb while shooting. Also on the back is a zoom lever, a playback button, a menu button, a special green mode/delete button (more about that later), and a five-way-plus-Ok pad to navigate the menu and to control settings such as flash, self-timer, and macro.

The tripod mount on the underside of the camera doesn't line up with the lens, but at least it's made of metal instead of strip-prone plastic. The battery/memory-card cover locks in place so that the compartment doesn't get soaked when the camera is submerged--but make sure it's secure before you take it for a dip.

Features
Despite its point-and-shoot status, the Optio W10 includes some very useful features and settings. Options include manual white balance; interval movie mode; automatic facial recognition/focus (one of the functions of the green button); and a selection of scene modes, ranging from the standard landscape and flower presets to natural skin tone, kids, pets and two special underwater settings. I like the built-in, green-button-activated guide that briefly explains each scene mode.

Performance
The Optio W10's sluggish performance incurs some painful waits between shots. Start-up to first shot takes about 3.5 seconds, and you can expect a 3.6-second shot-to-shot time after that, even in bright light. Shutter lag runs an acceptable 0.7 second in good lighting, though it quickly balloons to 1.6 seconds in dim environments. Burst mode is mediocre, cranking out a bit more than 1.1 frames per second for 7 frames.

Image Quality
The Optio W10's photo quality disappoints on a few fronts as well. Exposures are generally accurate, even in harsh afternoon lighting or under the gloom of monsoon rains. Colors that are generally difficult to capture correctly reproduce well; red tulips and lavender phlox rendered red and lavender, respectively. However, images suffer from a few serious postprocessing artifacts that not only soften the edges but obscure details and make the photos look out of focus.

The Pentax Optio W10 is a good camera for extreme shooting. Its design lets it shrug off water and dirt that would destroy other cameras. Its performance and image quality leave a lot to be desired, though, and you might want to look for another camera if you're not planning to go swimming with it.
