Sony a7 IV vs a7C Video Performance

The Sony a7 IV outperforms the Sony a7C in video capabilities, earning a score of 91/100 compared to the a7C’s 70/100. Both cameras share some common specifications, such as a maximum video resolution of 4K and dimensions of 3840 x 2160. Additionally, both cameras have built-in time-lapse functionality, making them suitable for capturing dynamic scenes over extended periods.

The Sony a7 IV excels in its video frame rate, offering a maximum of 120fps, which is significantly higher than the Sony a7C’s 30fps. This higher frame rate allows the a7 IV to capture smoother slow-motion footage, providing more flexibility for videographers who require precise control over their footage. The a7 IV’s superior frame rate contributes to its higher video score, making it the better choice for those prioritizing video performance.

While the Sony a7C has a lower video score and frame rate, it still delivers high-quality 4K footage at 30fps. This frame rate is sufficient for most casual users and some professionals who do not require the advanced slow-motion capabilities offered by the a7 IV. The a7C’s video capabilities are not necessarily inferior but cater to a different set of needs and preferences.

Comparing the video capabilities of both cameras, the Sony a7 IV is the clear winner for those seeking advanced video features and higher frame rates. However, the Sony a7C remains a viable option for users who prioritize other aspects of camera performance or have less demanding video requirements.
