The translucent mirror design, while enabling fast shooting, results in a slight reduction in light reaching the sensor compared to traditional DSLRs, impacting low-light performance. Battery life is moderate, requiring additional batteries for extended shoots. The camera’s body, although robust, is heavier than some competing models, potentially reducing portability. Its video autofocus is less smooth than dedicated video cameras, which may affect video quality. The proprietary A-mount lens system limits lens selection compared to more prevalent DSLR mounts. Some users note that the menu system can be complex and less intuitive for newcomers.

Despite these limitations, the A77 remains a strong option within its generation but may trail behind newer cameras in evolving feature sets.
