Sony a7 IV vs a7S III Overview and Optics

The Sony a7 IV outperforms the Sony a7S III in optics, scoring 85/100 compared to the latter’s 69/100. Both cameras share several specifications, such as a 10 fps shooting speed, CMOS sensor, Bionz XR processor, full-frame sensor size, Sony FE lens mount, and image stabilization.

The Sony a7 IV excels with its 33-megapixel sensor, providing higher resolution images compared to the a7S III’s 12.1-megapixel sensor. This difference allows for capturing more detail and enlarging photos without losing quality. Additionally, the a7 IV boasts a superior DXOMARK score of 97, indicating better overall image quality and performance than the a7S III’s score of 86.

Despite its lower score, the Sony a7S III has advantages in specific situations. Its 12.1-megapixel sensor offers larger individual pixels, leading to better low-light performance and less noise in high ISO settings. This makes the a7S III a strong contender for videographers and photographers working in challenging lighting conditions.

To conclude, the Sony a7 IV is the better choice for photographers seeking higher resolution and overall image quality. Its superior optics score and higher megapixel count make it ideal for capturing detailed images and enlarging photos without losing quality. On the other hand, the Sony a7S III is better suited for low-light situations and high ISO performance due to its larger individual pixels. Ultimately, the choice between these two cameras depends on the specific needs and preferences of the user.

Sony a7 IV vs a7S III Video Performance

The Sony a7 IV outperforms the Sony a7S III in video capabilities with a video score of 91/100, compared to the latter’s 77/100. Both cameras share some common specifications, such as 4K max video resolution, max video dimensions of 3840 x 2160, and a max video frame rate of 120fps. However, there are differences that make the Sony a7 IV the superior choice for videographers.

One significant advantage the Sony a7 IV has over the a7S III is the built-in time-lapse functionality. This feature allows users to create stunning time-lapse videos without the need for additional software or accessories, making it a more convenient and user-friendly option for capturing dynamic scenes and events.

While the Sony a7S III does not possess any notable advantages over the a7 IV in terms of video capabilities, it still offers excellent performance with its shared specifications of 4K resolution and 120fps frame rate. This means that the a7S III can still deliver high-quality video results, but it lacks the added benefit of the built-in time-lapse feature found in the a7 IV.

Considering the differences in video scores and the presence of built-in time-lapse functionality, the Sony a7 IV is the clear winner in this comparison. Videographers who prioritize convenience and a more comprehensive feature set will find the a7 IV to be the better choice. On the other hand, those who are not concerned with time-lapse functionality can still achieve impressive video results with the Sony a7S III, but should be aware of its limitations compared to its counterpart.
