The document compares the Canon EOS 550D and Canon EOS 1100D cameras. The 550D has higher specs like an 18 megapixel camera that can record 1080p full HD video at 30 frames per second, while the 1100D has 12 megapixels and can only record 720p HD video. The 550D also has a larger 3-inch LCD screen compared to the 2.7-inch screen on the 1100D. However, the 1100D has benefits like longer battery life, autofocus that works with more lenses, lighter weight, and a lower price. Sample photos are taken to check the image quality of the two cameras.
