Summary: Super clear pics. Can enlarge without a slight loss in quality. Lot to learn about it. Does not eat batterys. not to big. will take some time to figure out all the options but allows the novice to shoot right away.
Summary: I have been a Canon camera fan for years, my first SLR was a Canon, and so I was excited about 10 MP in a consumer-grade camera from Canon. After one week of average usage, here are the highs and lows. BTW, my frame of reference is my Canon G5. Highs- *- Incredible battery life. The camera comes with four alkaline (no name) batteries. I have taken more than 220 pictures and 30 minutes of video using the original batteries. *- 10 MP captures everything!
Summary: Coming from the Canon A80 from a few years ago... The A80 was a similar shape, size, and feature set but with only 4.0 megapixals, 3x lens, and a much smaller swivel viewing screen. Good Canon software has gotten better. What's better with the A640: It has similar features and body but a bigger screen and it is lighter. The screen is much bigger. The screen brightens nicely in dim and dark conditions. The flash works better and the flash assist lamp works MUCH better.
Summary: This is my first ever digital camera, but I did my research and I think I knew pretty much what I was getting into. The only reason I didn't give this camera 5 stars is it's less-than-stellar performance in low-light situations, and when the ISO was set 800. I knew about these problems before hand though so I can't complain too much. I love the pivoting lcd screen, it lets me shoot from all different angles, and also do self-portraits.
Sturdy build, nice images, great macro, pro-sumer quality.

Summary: This camera has the feel of a sturdy and well-built instrument that you don't mind taking into the field. It offers sufficient control--aperature, shutter speed, iso, exposure comp, file size, etc. --to make it a versatile companion and "spare camera" for pros and primary camera for most photo needs. Reasonable image quality (compared to my 5D) combined with great macro capacity, without OVER sharpening. (Canon could add/use a control here..
Best compact camera available for serious photographers

Summary: I've had this camera for over 2 months and I really enjoy using it. It's the compact camera available for serious photographers looking for advance features. The pics come out good and sharp, very big and with little noise if you shoot at 100 ASA. It's got all the necessary features including manual control...however the manual focus a bit cumbersome but available if nesecessary.
Summary: Update 12/01/08: This camera died while I was on my Thanksgiving trip in Paris. It won't power after I changed the batteries. Did everything on the manual and even went to a camera shop for help, but no avail. It was never dropped nor impacted and less than 2yrs old. Not a reliable product. -------------------------------------------------------------------------- There are still many functions I have yet to explore on this camera since I only own it for less than month.
Easy to use for a novice, great pictures for the price

Summary: I purchased this digital camera when it was reasonably priced, just before Christmas in 2006. My Vivitar 5MP had finally died after dropping it during our summer vacation so I was looking for something quick to have in time for the holidays. I got online to look at camera reviews and this model had excellent reviews from professionals, novices, and even beginners.
The Canon A640: A good camera with a poor microphone
Richard F., Amazon
22 January 2007
Summary: I purchased the 10MP Canon A640 camera in December 2006 to replace my 2MP Canon A40. I originally bought (and returned) a 6MP Canon A540 but it made noisy movies (i.e. you could hear the aperture and/or focusing mechanisms making clicking sounds when playing back the movies on a computer.) Unfortunately, my A640 suffers from a different problem with the movie mode: the movies have a high-pitched whine during playback on a computer. Also the sound is muffled.
Summary: Great Camera. I don't think anyone needs 10 mega pixels, but it is possible to set the pixel number much lower and save space on the computer. I've had the camera a couple of months and am still reading the instruction book. It sure has a lot of bells and whistles, but the basics are quite simple. I hope this will be my LAST camera. I especially like the size and fact that the little screne swivels and folds closed for your pocket.
