There are a lot of rugged point-and-shoot digital camera options this year, but while most manufacturers are new to the market, Pentax is on its 11th generation with the Optio W90. The 12-megapixel camera is waterproof down to 20 feet, shockproof to 4 feet, and freezeproof to 14 degrees Fahrenheit. It's got a body that can be held securely in and out of water and controls that are easily used with or without gloves. In fact, there's almost nothing worth changing about the design, and its feature set is robust for its class, going a bit beyond a basic point-and-shoot while still remaining simple to use.


Pentax Optio W90

The Good

Outstanding design; excellent feature set and shooting options for its class.

The Bad

Short battery life; no optical or mechanical image stabilization.

The Bottom Line

The well-designed Pentax Optio W90 offers up very good photos and performance at a reasonable price for a rugged pocket camera.

When it comes to rugged cameras, though, much of the price you pay goes for the protection and not photo quality or shooting performance. If you're considering the W90 as a primary camera, you may want to consider just how much you need the durable construction. Overall, the W90's photo quality and performance are very good for its class, but a nonrugged model with a shockproof/waterproof case might be a better fit. This one is really best suited for adventurers wanting a well-appointed point-and-shoot that they don't have to worry about knocking around or getting wet.

The W90 is built from reinforced polycarbonate plastic, though it does have a brushed-metal faceplate. The plastic could easily give the impression that it's a cheaply made camera, and it does make it feel slightly less rugged than the full-metal bodies of other rugged cameras. However, after testing, there is little doubt that the W90 can take the abuse Pentax claims, and the plastic keeps it very lightweight compared with metal-body models, so you won't be adding significant weight to your pocket or pack. A nice bonus is the included carabiner strap for quickly securing the camera to a bag or belt loop, and if you're afraid of dropping it while in the water, Pentax makes a floating strap for it as well. As with all rugged and waterproof cameras, there are handling precautions you need to take to keep water and dust out of the camera. These are clearly detailed in the front of the full, printed user manual that comes with the W90. (By the way, Pentax is one of the few manufacturers that still includes a full, printed manual with its cameras.)

In front is a 5x f3.5-5.5 28-140mm-equivalent lens protected by glass and surrounded by three LEDs that can be used to help brighten macro photos or as an impromptu flashlight. As with all rugged cameras, the lens is completely internal, but it's designed differently than typical internal lenses, allowing it to be positioned lower and more centered. This means the chances of getting fingers in your shots is far less likely to happen than on other internal lens cameras. On back is a reasonably bright 2.7-inch LCD. It has an antireflective coating, but you'll probably still struggle to see it in direct light.

Controls are easy to press with bare, gloved, or wet hands. They're fairly large considering the size of the camera's control panel. They're slightly raised from the body and well-spaced, so, again, pressing them isn't a problem. On top is the shutter release and power button, and the back has a zoom rocker; Play, Menu, and Face Detection buttons; a four-way directional pad with an OK button for selecting things; and Pentax's Green mode button.

The Face Detection options include a smile-activated shutter release setting, and the OK button doubles as a display button that cycles you through three information options as well as shutting the LCD entirely off, though I'm not sure how much use that is without an optical viewfinder. The directional pad navigates menus and photos and changes settings for the flash, focus, self-timer, and shooting modes. Lastly, the Green mode is Pentax's fully automatic you'll-get-no-control-over-anything-and-like-it shooting mode. What's great is that if you don't need that mode, Pentax lets you use it as a user-selectable shortcut button for accessing up to four settings such as exposure compensation, white balance, ISO, and metering.

The only real feature disappointment is the lack of optical or mechanical image stabilization. The camera instead has two electronic stabilization options. One is the traditional use of high ISOs and reduced resolution to keep shutter speed as fast as possible. It's effective to a point but really hurts image quality. The other option is Pentax's Pixel Track SR, which tracks motion blur at the pixel level, determining in real time the amount of blur. Once you've taken a shot, it filters the effect motion has on each pixel to sharpen them and remove blur (all of this takes a few seconds after the photo is captured). In my tests it works better than boosting ISO and shutter speed, as Pixel Track doesn't introduce more noise. However, in some of my shots it sacrificed sharpness in order to remove a slight blur. So it's not perfect, but it would be worth turning on if camera shake is unavoidable or if you're using the zoom lens.

The battery and memory card slots are behind a locking door in the bottom of the camera. Battery life is short; it's CIPA-rated for 205 shots, but using the LEDs, the zoom lens, shooting movies, etc., will bring that number down. If you're planning to take the W90 on a trip away from power outlets, you'll want to consider buying one or two extra batteries. Plus, the batteries aren't charged in the camera, so you'll need to take a charger with you, too. Under a locking door on the left side are Micro-HDMI and Micro-USB/AV ports. Cables for the latter are included, but you're on your own for the HDMI cable; Pentax sells one, but you can find it cheaper from other online retailers. A $29.95 waterproof infrared remote control is available, too, for those who want to shoot from a distance or reduce camera shake.

The W90's shooting modes are really geared for point-and-shoot users. You will not find any control over apertures or shutter speed with the exception of the Night Scene mode that uses up to a 4-second shutter speed. In fact, Pentax doesn't even bother sectioning off all its scene modes into a separate menu; they're simply lumped in with Pentax's scene-recognition Auto Picture mode and Program Auto. Program Auto gives you the most control over results, including settings for sharpness, contrast, and saturation. You can choose to shoot in three different color modes, but in playback you can apply several filters, including Sepia, Toy Camera, Retro, Color Extract, High Contrast, Soft, and Fisheye.

If you like to take a lot of close-ups, the W90's macro settings allow you to shoot as near as 0.4 of an inch from the camera and captures plenty of fine detail. One of the hyped features on this model is the Digital Microscope mode, which uses the three LEDs around the lens to brighten tiny subjects for macro shooting. The benefit of this mode over the regular macro options is that you can use the zoom lens to enlarge the subject before you shoot. The downside is the images are only 2 megapixels.

Shooting performance is very good for its class. From off to first shot is a fast 1.2 seconds. Shutter lag--how quickly a camera captures an image after the shutter-release button is pressed--is relatively low in bright conditions at 0.4 second and twice that in low light. Shot-to-shot times without the flash averaged 1.8 seconds and using the flash only pushed that up to 2.1 seconds.The W90's full-resolution continuous shooting is pretty quick at 1.4 frames per second with focus and exposure set with the first shot taken. The camera also has a 5-megapixel high-speed burst that shoots at up to 2.7fps for six frames.

The W90's photo quality is overall very good for a compact rugged camera. Point-and-shoots often produce soft-looking photos, and rugged cameras are even more prone to do so. While the W90 isn't an exception, it is better than most. Noise will likely be a bigger concern for pixel peepers as it creeps in at ISO 80. Pentax does a good job of controlling it at the lower ISOs, though, without affecting fine detail. At ISO 400 there's a noticeable increase in softness, which continues up to ISO 1,600, the highest available ISO at full resolution. When photos are viewed at small sizes there's still perceived detail at the highest sensitivities, but colors look washed out, making the photos of little use. Still, this is a camera designed for outdoor use, and the W90 does very well when it has a lot of light.

The W90's wide-angle lens does exhibit some barrel distortion, but it's tough to see it because Pentax corrects it in still photos. The same for pincushioning when the lens is zoomed out. However, shoot a movie and you'll see it pretty easily. On the upside, the lens is pretty sharp and stays that way edge-to-edge and in the corners. Purple fringing is minimal as well and definitely below average for its class.

Colors weren't accurate from the W90 in our lab tests with the exception of neutrals. The default color mode is Bright, and it definitely churned out more pleasing results than the Natural option, which tended to look flat and cool. Exposure was good, but white balance seems a bit hit or miss. The auto white balance was very warm under incandescent light, but the tungsten preset leaned toward cool. Outdoors, auto white balance performs better. However, and probably unsurprisingly, the manual white balance works best in all settings.

Much like the photo quality, the W90's 720p HD video quality is good, but soft with a high level of noise in low-light conditions. It's on par with an average HD pocket video camera, though with this you'll be able to shoot in inclement weather or underwater without worrying about it. Unfortunately, the zoom doesn't work while recording, which is odd; most internal-zoom-lens cameras allow that feature. You do get digital image stabilization, though, and you can choose between 15fps or 30fps.

For the most part with rugged cameras, photo quality and shooting performance take a back seat to making the camera durable. The Pentax Optio W90 offers a lot of protection without having to sacrifice much on either of those things.
