Editorial note
The Sony Alpha A57 is a DSLR camera that stands out for its exceptional image quality, offering a resolution of 16.1 MP thanks to its CMOS sensor. Photographers will appreciate the flexibility of the autofocus modes, including effective tracking, which ensure sharp images in various situations. Additionally, the built-in image stabilizer allows for capturing smooth photos and videos, even in motion. However, this device has some drawbacks. Its weight of 618 g may make it less practical for extended use or when traveling. Furthermore, while manual focus offers precise control, it may be less intuitive for some users. The maximum video resolution of 1920 x 1080 pixels, while acceptable, may disappoint those looking for 4K quality. The 3-inch LCD screen, while functional, could benefit from improved size and responsiveness. Finally, the lack of Wi-Fi connectivity limits the quick sharing of photos and videos. Overall, the Sony Alpha A57 is a solid choice for amateur and semi-professional photographers, thanks to its performance and varied features. However, users seeking a more intuitive experience and modern connectivity may want to consider other options.Score details
