Limitations

The Sony a1 II's high-resolution sensor generates large file sizes requiring substantial storage and processing power. The camera's advanced features and specifications make it relatively expensive, which may limit accessibility for hobbyists. Battery life is moderate given the intensive processing demands, requiring multiple batteries for extended shoots.
