We haven't had our hands on this product, but we know which features matter. Here's how the measures up:
Average Resolution Allows You to Make Small and Medium Prints
This point-and-shoot model has an average megapixel count for its class. You can print images from an 8- to 10-megapixel camera at sizes up to 8 by 10 inches with no loss in quality; at 13 by 19 inches, however, prints will lose a slight amount of detail. As the pixel count on an image sensor increases, so does its tendency 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.
Small LCD Screen
In the universe of digital cameras, this model has a fairly small LCD screen. It’s tempting to think that bigger is better, but there are advantages to having a smaller 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.
Limited Ability to Zoom
The optical zoom range on this camera is rather limited, though it should be adequate to handle everyday situations such as snapshots, group pictures, and typical informal photos. 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 considerably closer than you’d be able to with the naked eye--but nowhere near as close as a specialty camera for sports or nature photography could.
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: Small size, easy to use, good battery life
Weaknesses: Night photography ... doesn't quite give the quality
Overall: Hi ... I've been using this camera for over a year now .. and it hasn't given me any problems yet . Its a nice camera offering 4 MP resolution, its sleek and easy to use. The only problem I've observed is, picture quality is not very impressive when the light is weak ... but then no point n shoot camera gives u good quality photos in dim light... u need a SLR for that Its a gr8 value for money ... and defenitely worth a buy

Strengths: lightwieght, handy
Weaknesses: no rechargeable batteries included, and only accepts sony memory stick, no macro shot,no blurred motion shot
Overall: this is my first digicam...i think i am going to sell this camera and buy another brand...for one, the memory stick is too expensive, and i hope it accepts other memory stick... it has no macro shot unlike other competitive digicam... when you take objects in motion, it will result to a blur unlike other leading digicam...

Strengths: light weight, long battery life
Weaknesses: only 3X optical zoom, only sony memory stick is available
Overall: The camera has a good feeling, light weight, compact size, easy operating. maybe 3X zoom is not enough, no rechargable battery, however I have to say it is excellent for a 4.1 MP camera at such a low price.
