We haven't had our hands on this product, but we know which features matter. Here's how the measures up:
High Resolution Allows You to Make Large Prints
For a point-and-shoot camera, this model has a high megapixel count. You can print images from an 8- to 13-megapixel camera at sizes up to 8 by 10 inches with no loss in quality; at 13 by 19 inches, however, prints will exhibit a slight loss of detail. Images from a 13-megapixel camera look good at 13 by 19 inches and can be pushed to 16 by 24 inches. Though prints at these larger sizes will lose some sharpness, they'll be superior to what you'd get from 35mm film printed at the same dimensions. You’ll also have plenty of latitude to crop and resize images. As the pixel count on an image sensor increases, so does its propensity to produce images plagued by noise--ugly speckling patterns. To avoid noise, look for a camera with the lowest pixel count that still serves your output needs.
Average-Size LCD Screen
This model's LCD screen is of average size for a point-and-shoot digital camera. It’s tempting to think that bigger is better, but there are advantages to having a modest-size screen. What you lack in big-screen bang may likely come back to you in longer battery life: Powering a big, bright LCD takes a lot of juice. When a camera's LCD screen has its only viewfinder, you need to make sure that you can see it easily in bright daylight and in very low ambient light. Use the LCD screen to judge the composition of your images but not to gauge color and exposure. For color and contrast, histograms of your images are much more reliable--and most cameras these days provide them.
Medium-Size Optical Zoom Range
The optical zoom range on this camera is average, supporting a reasonable range of wide-angle and telephoto shots. You still won’t have the telephoto power that you'd get from a specialty camera for sports or nature photography, however, nor will you be able to take the wide-angle shots frequently found in architectural or landscape photography. Most point-and-shoots offer a focal length range that’s roughly equivalent to 35mm to 105mm on a 35mm film camera. At the wide end (the 35mm, in this case), they shoot a bit wider than what you see with your eye. At the telephoto end (the 105mm, in this case), they can zoom in a good deal closer than you’d be able to with the naked eye.
Medium Continuous Shooting Speed
When a camera is in burst (or drive) mode, it will continue to shoot as long as you hold down the shutter button. How quickly a particular model takes pictures in this mode depends on its continuous shooting speed, measured in number of frames per second (fps). This camera has a moderate continuous shooting speed. With a burst speed of 2 to 4 fps, a camera stands a better chance of recording a series of subtle changes in expression when photographing people, and it is much more likely to capture decisive sports and entertainment moments.
Optical/CCD Image Stabilization
Some cameras rely on lens-based optical image stabilization. This camera, however, employs sensor-based stabilization, which works by moving the camera’s internal image sensor to compensate for shake. A charge-coupled device (CCD) within the camera body handles the image shifting. Optical image stabilization is very useful when you're taking pictures with a telephoto lens or trying to capture high-zoom shots; in both of these situations, even a very slight shake will result in a blurry image. CCD-based image stabilization can save you money because it doesn't require a special lens for stabilizing images (stabilized lenses usually cost more than nonstabilized lenses).
JPEG Image Format
All digital cameras can capture JPEG images. The JPEG compression process greatly reduces the amount of storage an image requires, and JPEG images transfer quickly from your camera to your computer. JPEG compression is a lossy algorithm, however, which means that saving an image in JPEG format degrades its quality. The high-quality JPEG settings on most cameras are quite good, and it's difficult to spot differences between a JPEG compressed image and a noncompressed image. Still, if you like to edit your images, you may want to upgrade to a camera that also supports a noncompressed (lossless) format, such as TIFF or RAW.
High Video Frame Rate
The video mode on this camera has a high maximum frame rate. Ideally, a camera's video mode would capture video at 30 frames per second (the frame rate of video you see on TV). At this frame rate, output would be of good quality, and you’d be able to intercut it with video from a camcorder and not see a big difference in smoothness of motion between the two clips. Movies, on the other hand, have a frame rate of 24 frames per second, and you need a rate of about 18 frames per second to record video with synchronized sound. A faster frame rate makes for smoother pans and smoother capture of fast-moving objects.
Great For Macro Photography
This model has a better-than-average minimum focus distance, meaning that it can focus on subjects very close to the lens--great for macro photography. To test the unit's minimum focus distance, position it very close to a subject, and press the shutter button halfway down to focus; if the camera never beeps to indicate that the image is in focus, you are closer than the camera’s minimum focus distance. If this happens, switch the camera to macro mode and try again. If the camera won’t focus even in macro mode, you can sometimes zoom in or out to get it to lock into focus.

Strengths: 5X optical, image stabilization, feature set
Weaknesses: Battery
Overall: This is the perfect camera for professional quality but the versatility of extremely small size. Fits in a cyclist jersey pocket and doesn't weigh you down! All weather housing makes it possible to carry it through rugged conditions without worrying about ruining it.
