Bests & Worsts Reviews from Amazon

After extensive research on the web ...I chose to upgrade my Canon S20 to a Canon S400. In someways, this was a step down. Unfortunately, the S400 does not support verticle alignment of it's panoramic "stitch assist" mode as they do on the S40, S45, S50 and other higher priced models. I found this feature on the S20 to be very useful in capturing more image (greater resolution and consistant panning) when stitching photos together to make a panoramic photo. Also, the S400 does not support the higher resolution movie mode of 640 x 320, as some digital cameras support. Hopefully, Canon will address these feature shortfalls with a firmware upgrade in the near future. As mentioned in a number of reviews, the S400's flash is miniscule and thus is somewhat inadequate to light wide distant shots. Canon has improved the intelligence of the powershot digital line. Specifically in the S400 the Digic processing makes for fast picture taking and viewing. The size of the S400 is grand. It does fit in a pocket and powers up so quickly, you may never miss another shot with this camera (keeping in mind to charge your battery and have enough flash memory for the moment!!!). The bottom line... the Canon S400 is compact, sturdy, and fast. If you are looking for a very small 4 megapixel camera with nice even colors, low levels of distortion, a basic movie capture mode, fast memory writing and reading, the S400 is a current top pick. However, if you are looking for lots of manual control, vertical "photo stitching," and more pixels try the S50. One note if considering the S45 or S50 cameras, play with the navigation buttons before purchasing the unit; I have found the navigation to be somewhat clumsy in-which it is easy to hit "enter" when trying to navigate "up" or "down," or hit "up" when trying to "enter."
