Sensor and Image Quality
Both the A550 and A580 boast a 14.2-megapixel CMOS sensor, offering comparable image quality. However, the A580 features a slightly larger sensor size, resulting in a slightly shallower depth of field at wider apertures. This subtle difference may be noticeable in certain shooting scenarios, such as portraits or close-ups.
Autofocus System
The A550 employs a phase-detection autofocus system with 9 focus points, while the A580 boasts a more advanced phase-detection system with 15 focus points. The additional focus points in the A580 provide greater flexibility and accuracy, particularly when tracking moving subjects.
Continuous Shooting Speed
The A550 offers a continuous shooting speed of 5 frames per second (fps), while the A580 delivers a slightly faster 7 fps. This difference may not be significant for casual shooting, but it can be advantageous for capturing fast-paced action or sports events.
Live View and Video Capabilities
Both cameras feature a Live View mode, allowing you to compose and preview images on the rear LCD screen. The A580 adds an electronic viewfinder (EVF), providing an alternative to the optical viewfinder. Additionally, the A580 offers enhanced video capabilities, including 1080p Full HD video recording, making it a more versatile choice for videographers.
