Limitations

The battery life of the a6400 is moderate, providing around 360 shots per charge, which may require carrying extra batteries for extended shoots.

It lacks in-body image stabilization, relying instead on lens stabilization, which may impact handheld shooting performance in some situations.

The camera does not have a built-in flash, requiring external lighting accessories in low-light environments.

The 180-degree flip screen, while great for selfies, does not fully articulate for side or downward shooting angles.

Video recording is limited to 30 minutes per clip at 4K resolution, which may constrain longer recordings.

The microphone input is single 3.5mm jack without headphone output, limiting on-set audio monitoring capabilities.
