The Sony Alpha A77 boasts a high-resolution 24.3 MP APS-C sensor that delivers detailed images. Its translucent mirror technology allows for ultra-fast continuous autofocus and shooting. The electronic viewfinder provides real-time exposure and settings previews with 100% frame coverage. Full HD 1080p video recording with stereo sound enhances multimedia versatility. A robust 12 fps burst shooting supports fast action capture, making it suitable for sports and wildlife photography. Additionally, the camera supports anti-dust technology and in-body lens image stabilization enhancing image clarity.

Despite its advanced features, the Sony Alpha A77 has some limitations. The use of an electronic viewfinder rather than an optical one may cause latency and reduced battery life. Its proprietary A-mount lens system limits lens compatibility compared to more widespread mounts. The camera's weight and size are relatively large for an APS-C format DSLR, potentially reducing portability. Video recording options lack some professional features like 4K resolution or advanced codecs. Additionally, its ISO range, while broad, can produce noise at very high sensitivities. The fixed translucent mirror design also results in reduced light transmission compared to traditional DSLRs, slightly affecting low-light performance.
