Sony a7R II vs a7S Overview and Optics

The Sony a7R II emerges as the winner in the optics comparison, with a score of 81/100, while the Sony a7S trails behind at 60/100. This 21-point difference highlights the superiority of the a7R II in terms of optical performance. Both cameras share several specifications, including a shooting speed of 5, a CMOS sensor type, a Bionz X processor, a full-frame sensor size, and a Sony FE lens mount.

The a7R II outperforms the a7S in several aspects. With a higher megapixel count of 42.4, compared to the a7S’s 12.2, the a7R II captures significantly more detail and produces higher-resolution images. The a7R II also boasts a superior DXOMARK sensor score of 98, as opposed to the a7S’s score of 87, which reflects its better overall image quality. Additionally, the a7R II features image stabilization, providing an advantage when capturing images in low-light conditions or with longer focal lengths.

On the other hand, the a7S does not offer any clear advantages over the a7R II in terms of optics. Both cameras share the same shooting speed, sensor type, processor, sensor size, and lens mount. However, it is worth noting that the a7S’s lower megapixel count may be advantageous for those prioritizing low-light performance and video capabilities, as fewer megapixels can result in better low-light sensitivity and reduced noise.

Taking all these factors into account, the Sony a7R II stands out as the superior option for photographers seeking higher-resolution images, better image quality, and image stabilization. The Sony a7S, while lacking in optical advantages, may still be a suitable choice for those prioritizing low-light performance and video capabilities.
