Hi, Here is a comparison that you can look at: http://www.dcresource.com/reviews/compare.ph
I have added the Canon SD700IS because I think that it is better built than the SD800IS.
These cameras are close in size and all are very good looking cameras, for some reason and I don't know why, the Fujifilms LCD screen looks bigger, but it's not.
Also, the Fujifilm F30 and the Canon SD800IS are on Jeff's (site mentioned above) top ten list.
Read the reviews for each one and it could help you decide what's important to you in a camera
I hear that the Fujifilm F30 is better in low light.. at this point which do u think is more attractive? because I am really having trouble choosing between the two. Are there any better ultra compact and slim cameras out there?
