Sony a7S III vs a7S II Overview and Optics

The Sony a7S III outperforms the Sony a7S II with a score of 69/100 in optics compared to the latter’s 66/100. Both cameras share several features, including 12.1 and 12.2 megapixels, CMOS sensors, full-frame sensor sizes, Sony FE lens mounts, and image stabilization.

The Sony a7S III excels due to its improved shooting speed of 10 fps, compared to the a7S II’s 5 fps. This allows for capturing fast-moving subjects and action scenes more effectively. Additionally, the a7S III is equipped with a more advanced Bionz XR processor, enhancing image processing and overall performance. Its DXOMARK sensor score also surpasses that of the a7S II at 86 versus 85, implying better image quality.

The Sony a7S II, despite its lower score, has a slight advantage in megapixels at 12.2, which may contribute to marginally better image resolution. However, this difference is minimal and unlikely to impact overall image quality significantly.

In comparing optics, the Sony a7S III clearly outshines its predecessor due to its faster shooting speed, superior processor, and marginally better DXOMARK sensor score. While the Sony a7S II has a negligible advantage in megapixels, it does not outweigh the benefits provided by the a7S III’s improvements. As a result, the Sony a7S III is the better choice for those seeking enhanced performance in optics.

Sony a7S III vs a7S II Video Performance

The Sony a7S III outperforms the Sony a7S II in video capabilities, with a video score of 77/100 compared to the a7S II’s 56/100. Both cameras share some common specifications, such as a maximum video resolution of 4K and dimensions of 3840 x 2160. Neither camera has built-in time-lapse functionality.

The a7S III’s higher video score is primarily due to its significantly better maximum video frame rate of 120fps, compared to the a7S II’s 30fps. This higher frame rate allows for smoother and more detailed videos, particularly in fast-moving scenes or when capturing slow-motion footage. This improvement in frame rate makes the a7S III a more versatile and powerful camera for videography.

The a7S II, on the other hand, does not offer any advantages over the a7S III in terms of video capabilities. Its video score is lower, and its maximum frame rate is significantly less than that of the a7S III. The only similarity between the two cameras in this regard is their shared max video resolution and dimensions, as well as the lack of built-in time-lapse functionality.

Taking these factors into account, the Sony a7S III is the clear winner when it comes to video capabilities. Its superior maximum frame rate of 120fps provides a significant advantage over the a7S II’s 30fps, making it a more versatile and powerful option for videographers. The a7S II, while still offering 4K video resolution, falls short in comparison due to its lower video score and limited frame rate.
