While the 12.1MP sensor delivers excellent video quality and low-light performance, it might be less ideal for photographers requiring very high resolution images. The price point is relatively high, which could be a barrier for hobbyists or beginners. Battery life, although improved, can still be limiting for extended outdoor shooting without additional power solutions. The camera's extensive feature set comes with a learning curve for users new to professional-grade cameras. Some lens options can be costly and may require additional investment for optimized performance. Additionally, the camera's file sizes for 10-bit 4K video recordings are large, needing high-capacity and fast storage solutions which might increase total production costs.
