Sony a7 II vs a7S III Video Performance

The Sony a7S III outperforms the Sony a7 II in video capabilities with a 21-point advantage in video score (77/100 vs 56/100). Both cameras share some common video specifications, such as the lack of built-in time-lapse functionality. However, the Sony a7S III surpasses the a7 II in other crucial aspects, leading to its higher score.

The Sony a7S III offers 4K video resolution with a maximum video dimension of 3840 x 2160, while the Sony a7 II only provides Full HD resolution with a maximum video dimension of 1920 x 1080. This difference means that the a7S III can capture more detailed and higher-quality video footage compared to the a7 II. Additionally, the a7S III has a significantly higher maximum video frame rate of 120fps, double the a7 II’s 60fps. This allows the a7S III to record smoother slow-motion footage and capture fast-moving subjects more effectively.

On the other hand, the Sony a7 II still has some benefits despite its lower video score. Its Full HD resolution and 60fps frame rate are sufficient for casual video recording and general use. Users who do not require 4K resolution or high frame rates may find the a7 II more than adequate for their needs.

Considering the video capabilities of both cameras, the Sony a7S III is clearly the superior choice for those seeking higher-quality video footage, better resolution, and smoother slow-motion recording. However, the Sony a7 II remains a viable option for casual video recording and general use where advanced video features are not a priority.
