Performance
The first thing I check when reviewing the performance of any digital camera are the colors and the level of sharpness, because at the end of the day, these two things are what matter the most. And those are precisely the two points that I found the most impressive about the Canon A640.
While the above image is a great example of edge-to-edge sharpness, the macro shot taken below shows you the quality of the camera's macro focus level. As mentioned above, the A640 shoots macro shots of objects as close as a centimeter away, and the shot below proves that it definitely doesn't compromise on quality while at it.
While the camera has manual exposure and manual focus, it's shooting presets do a pretty good job of adjusting the camera for the required shot. The shot below was taken using the Landscape mode and as you can see, the focus is evenly maintained throughout the scene, which is exactly the requirement in this case.
Getting back to the colors, the Canon A640 makes the most of the available light to bring out the best and most accurate colors. The reds, pinks and oranges are easily distinguishable in the test shots and even the faint color gradients were captured quite accurately.
When shooting in the dark, the camera's night mode did a pretty good job of making the most of the available light. However when I manually raised the ISO levels for a low light shot, the image contained a lot of digital noise, which was pretty sad to see in a camera that performed pretty well otherwise.
Conclusion
