Sony a6400 vs a7S II Overview and Optics

The Sony a6400 wins in the optics comparison with a score of 68/100, while the Sony a7S II follows closely behind with 66/100. Both cameras share some common specifications, such as the CMOS sensor type, Bionz X processor, and compatibility with Sony lenses. However, there are key differences that set them apart.

The Sony a6400 outperforms the a7S II in terms of megapixels and shooting speed. With 24.2 megapixels, it produces higher resolution images compared to the a7S II’s 12.2 megapixels. The a6400 also boasts an impressive shooting speed of 11 frames per second, more than double the a7S II’s 5 frames per second. These factors contribute to the a6400’s superior performance in capturing detailed and fast-paced subjects.

On the other hand, the Sony a7S II has the edge in sensor size and image stabilization. The full-frame sensor provides a larger surface area for light collection, resulting in better low-light performance and increased dynamic range. Its DXOMARK score of 85 supports this advantage. Additionally, the a7S II offers built-in image stabilization, which compensates for camera shake and allows for sharper images in various shooting conditions. The a6400 lacks this feature, which may limit its performance in certain situations.

Despite the close scores, each camera excels in different areas. The Sony a6400 is the better choice for capturing high-resolution images and fast-paced action, while the Sony a7S II is more suitable for low-light photography and situations where image stabilization is crucial. Ultimately, the right choice depends on the specific needs and preferences of the photographer.
