Sony a7R II vs SLT Alpha 99 II Video Performance

The Sony SLT Alpha 99 II outperforms the Sony a7R II in video capabilities with a score of 77/100, compared to the a7R II’s score of 56/100. Both cameras share some common specifications, such as 4K max video resolution and 3840 x 2160 max video dimensions. However, there are key differences that contribute to the Alpha 99 II’s superior video performance.

The most notable advantage of the Alpha 99 II is its max video frame rate of 120fps, while the a7R II only offers 30fps. This allows the Alpha 99 II to capture smoother, more detailed slow-motion footage, making it a better choice for videographers who require high-quality slow-motion capabilities.

On the other hand, both cameras lack built-in time-lapse functionality. This means that users seeking to create time-lapse videos will need to resort to external software or devices to achieve this effect, regardless of which camera they choose.

In terms of video performance, the Sony SLT Alpha 99 II clearly surpasses the Sony a7R II, mainly due to its higher max video frame rate. The Alpha 99 II caters to videographers who demand advanced slow-motion capabilities, while the a7R II falls short in this aspect. Despite both cameras lacking built-in time-lapse functionality, the overall video performance of the Alpha 99 II makes it a more suitable choice for videography purposes.
