Canon Powershot A630 Reviews
Please help me decide which of the three digital cameras is the best?

I want to buy a good digital camera. I've heard good things about Canon PowerShot SD750 / SD 800 / SD 850, Canon PowerShot A630/640, and Sony Cybershot DSC T100. These seem to be the top three models based on comments. Can anyone help me decide which is better? Or if there is another model which is also good or even better? Thanks in advance for your help!

I favor the Canon SD750. There great video review of the camera on this page. What helped me decide. http://canon-directory.com/store/Canon/canon-SD750-digital-elph-camera

Canon Powershot A630 Reviews

My job as the camera is not it?

I recently bought the Canon Powershot A630, and its very nice, but I few questions. How can know the difference between superfine, fine and normal? I took the photo of the tree even using different modes, and when I checked the images on the screen of my TV and computer, I could not make a difference in quality. The pictures are great, but if I can define the configuration of superfine, Im more megapixels (Assuming Im), so I can not take many pictures? Do I set to Normal and I do not seem to be able to tel the difference, or am I missing something? In addition, if configured for different sizes (large, averages, etc.) all look the same size image on the computer screen.

I have the feeling you want to see the difference between modes of transport if you were climbing the photos to a website or printed on photo paper.
