The camera offers a 3-inch tilting LCD screen and an electronic viewfinder with 1.44 million dots providing a clear live view. It supports HD video recording up to 1080i and a continuous shooting speed of up to 10 frames per second. The body benefits from compactness due to the lack of a traditional DSLR mirror mechanism.

Key Advantages
The alpha SLT-A55 stands out for its fast continuous autofocus in video thanks to the translucent mirror system. It delivers high resolution images with its 16.2MP APS-C sensor. The electronic viewfinder provides real-time exposure and focus preview, which is an advantage over optical viewfinders. Its high-speed continuous shooting at 10 fps is excellent for action photography. The camera's tilt LCD screen adds flexibility for varied shooting angles. Additionally, the compact and lightweight design improves portability compared to traditional DSLRs.
Limitations
The SLT-A55’s electronic viewfinder may experience lag or pixelation in certain lighting conditions compared to optical viewfinders. Battery life is shorter due to the constant usage of the electronic viewfinder and translucent mirror system. The camera’s low-light ISO performance is moderate and may introduce noise at higher settings. Video recording is limited to 1080i resolution rather than progressive scan full HD. The autofocus system, though fast, may struggle with very fast or erratic moving subjects. Also, the proprietary lens mount limits lens choices to Sony A-mount lenses.
