Drawbacks of the Sony Alpha a7S III

5. Complex Menu for Beginners: While improved, Sony’s menu system can feel overwhelming for new users compared to Canon’s more intuitive interface.
6. Battery Life: The NP-FZ100 battery lasts for about 600 shots or 90 minutes of 4K video, requiring spares for long shoots compared to competitors like the Fujifilm X-S20 (750 shots).
