A review of the Canon PowerShot SD400 digital camera is available at imaging resource.

Here is the advice of the reviewer:
“[…] The ability to adjust ISO, White Balance, and access longer shutter times significantly increases the camera’s shooting range.
[…] It’s also quite responsive for a subcompact digital camera, and its movie capability goes far beyond what I’m accustomed to seeing from subcompact digital camera models
[…]It’s a nice camera, a good value, and a good option if the $100 higher price of the SD500 puts that model out of your price range.
Bottom line, a very nice little camera, another Dave’s Pick for Canon.”
