Sony a7C vs a7R III Overview and Optics

The Sony a7R III outperforms the Sony a7C in optics with a score of 84/100 compared to the a7C’s 80/100. Both cameras share several specifications, including a CMOS sensor, Bionz X processor, full-frame sensor size, Sony FE lens mount, and image stabilization. Despite their similarities, the a7R III emerges as the superior camera in terms of optics.

The a7R III’s advantage lies in its higher megapixel count of 42.4, compared to the a7C’s 24.2 megapixels. This results in sharper, more detailed images captured by the a7R III. Additionally, the a7R III boasts a higher DXOMARK sensor score of 100, compared to the a7C’s score of 95. This higher score reflects the a7R III’s better overall image quality and dynamic range, enabling photographers to capture more information in a single shot.

While the a7C falls short in comparison to the a7R III in terms of optics, it does match the a7R III’s shooting speed of 10 frames per second. This means both cameras can capture fast-moving subjects with equal efficiency.

Considering the points above, the Sony a7R III proves to be the better camera in terms of optics due to its higher megapixel count and DXOMARK sensor score. This makes it ideal for photographers seeking greater image quality and detail. On the other hand, the Sony a7C provides similar shooting speed performance, making it a suitable choice for those prioritizing speed over image resolution. Ultimately, the decision between these two cameras depends on the specific needs and priorities of the photographer.

Both cameras share several video features, such as 4K max video resolution, 3840 x 2160 max video dimensions, and a max video frame rate of 30fps. However, there are differences that give the a7C an advantage over the a7R III.

The a7C has a built-in time-lapse functionality, which is absent in the a7R III.

Both cameras have the same max video resolution, dimensions, and frame rate, making their performance in these aspects equal. The lack of built-in time-lapse functionality puts the a7R III at a disadvantage compared to the a7C.

The Sony a7C’s higher video score reflects its superiority in video features, specifically the built-in time-lapse functionality. This makes it a more versatile option for videographers seeking creative freedom. Meanwhile, the Sony a7R III does not provide any notable advantages in the video department, making it a less attractive choice for those prioritizing video capabilities.
