The Sony a7S II, despite its lower score, might appeal to some users due to its more recent release date. This could indicate potential improvements or additional features not present in the a7 II.

Taking these points into consideration, the Sony a7 II is the better choice for those seeking a lighter and more affordable camera, while the a7S II could be suitable for users looking for a more recent model.

Sony a7 II vs a7S II Overview and Optics

The Sony a7 II outperforms the Sony a7S II in optics with a score of 78/100 compared to 66/100. Both cameras share several specifications, including a shooting speed of 5 frames per second, a CMOS sensor, a Bionz X processor, full frame sensor size, Sony lens mounts, and image stabilization.

The Sony a7 II’s superiority in optics is primarily due to its higher megapixel count of 24.2 compared to the Sony a7S II’s 12.2. This difference allows the a7 II to capture more detailed images, making it more suitable for photography enthusiasts who prioritize image quality. Additionally, the a7 II has a higher DXOMARK score for its sensor at 90, compared to the a7S II’s score of 85. This further indicates that the a7 II has a better overall sensor performance, which contributes to its higher optics score.

However, the Sony a7S II has its advantages as well. With its lower megapixel count, the camera is more adept at handling low light situations and producing less noise in images. This makes the a7S II a better option for those who frequently shoot in low light or prioritize video recording, where higher megapixel counts are less critical.

Taking all of these factors into consideration, the Sony a7 II is the better choice for those who prioritize image quality and detail in their photography, thanks to its higher megapixel count and better overall sensor performance. On the other hand, the Sony a7S II is more suitable for low light shooters and videographers, as its lower megapixel sensor allows for better low light performance and less image noise.

The higher the number of megapixels, the more detail the cameras sensor can capture.

Aspect Ratio
The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.

Sony a7 II vs a7S II Video Performance

The Sony a7S II wins the video capabilities comparison with a score of 86/100, while the Sony a7 II scores 56/100. Both cameras share some common video specifications, such as lacking built-in time-lapse functionality.

The Sony a7S II outperforms the a7 II in terms of video resolution and dimensions. It offers 4K video resolution (3840 x 2160) compared to the a7 II’s Full HD (1920 x 1080). This means that the a7S II delivers a significantly higher level of detail and clarity in video recording, making it ideal for professional use and high-quality content creation.

On the other hand, the Sony a7 II has a higher maximum video frame rate at 60fps, compared to the a7S II’s 30fps. This allows the a7 II to capture smoother video footage, especially when recording fast-moving subjects or action scenes. However, this advantage comes at the cost of lower video resolution and dimensions.

In terms of video performance, the Sony a7S II is the clear winner due to its superior video resolution and dimensions, making it a better choice for professional videographers and content creators. The Sony a7 II, with its higher frame rate, may be suitable for those who prioritize smooth video footage over resolution, but its overall video capabilities are less impressive than the a7S II.

Thus, the Sony a7S II is the better option for users who demand high-quality video performance, while the Sony a7 II might be more suitable for casual users or those who prioritize smoothness in their video recordings.
