Chiếc máy ảnh ống kính rời mới nhất của Canon có cảm biến APS-C 18 triệu điểm ảnh và bộ vi xử lý ảnh DIGIC 4, khá giống với chiếc DSLR ra mắt cách đây ít lâu của hãng là EOS 7D. Model này còn có khả năng quay video Full HD 1080p với tốc độ 30, 25 và 24 khung hình/ giây.

Canon EOS 550D sở hữu hệ thống đo sáng 63 vùng iFCL với cảm biến kép để tránh phơi sáng quá lâu với những cảnh màu đỏ chiếm ưu thế. Máy có khả năng chụp liên tiếp với tốc độ 3,7 khung hình/giây với phạm vi ISO tiêu chuẩn là từ 100-6400 (mở rộng lên tới 12800). Tính năng Auto ISO vẫn tiếp tục được tích hợp trên 550D để giúp giảm thiểu thời gian tinh chỉnh cho người sử dụng.

Máy sẽ xuất hiện trên thị trường với giá 800 USD cho riêng body và 900 USD kèm ống kit.
