Samsung S800 vs Canon EOS 5D cameras reviews
We like more Canon EOS 5D's 2.5" screen than Samsung S800's 2.4" size.
Camera on Canon EOS 5D is able to make better quality pictures with its 12.8 megapixels rather than Samsung S800 with 8.1 megapixels.
Samsung S800 has optical zoom of 3x and Canon EOS 5D doesn't have any. For Canon EOS 5D you should buy special external lenses. You choose lenses by your needs and preferences. That is the characteristic of some professional models.
