Sony a6400 vs a7 II Overview and Optics

The Sony a7 II comes out on top in our optics comparison with a score of 78/100, while the Sony a6400 receives a score of 68/100. Both cameras share several specifications, including 24.2 megapixels, CMOS sensor type, Bionz X processor, and Sony E lens mount.

The winning camera, Sony a7 II, boasts a higher DXOMARK score for the sensor at 90, compared to the a6400’s score of 83. This difference results in improved image quality from the a7 II. Additionally, the a7 II features a full-frame sensor, which contributes to better low-light performance and increased dynamic range. Another advantage of the Sony a7 II is its built-in image stabilization, allowing for steadier shots and reduced camera shake in various shooting conditions.

On the other hand, the Sony a6400 has a faster shooting speed of 11 frames per second, compared to the a7 II’s 5 frames per second. This makes the a6400 better suited for capturing fast-moving subjects and action photography.

The Sony a7 II’s superior sensor quality and built-in image stabilization make it the better option for photographers seeking optimal image quality and low-light performance. However, the Sony a6400’s faster shooting speed may be more appealing to those who prioritize capturing fast-paced action. Both cameras offer excellent optics, but the a7 II’s advantages in sensor quality and stabilization give it the edge in this comparison.

Sony a6400 vs a7 II Video Performance

The Sony a6400 triumphs over the Sony a7 II in video capabilities, with a video score of 91/100 compared to the Sony a7 II’s 56/100. Both cameras have some similarities in their video features, but the Sony a6400 has several advantages that contribute to its higher score.

Both cameras share max video resolutions, with the Sony a6400 offering 4K (3840 x 2160) and the Sony a7 II providing Full HD (1920 x 1080). Additionally, they both have max video frame rates, with the Sony a6400 reaching 120fps and the Sony a7 II at 60fps.

The Sony a6400 outperforms the Sony a7 II due to its higher max video resolution, allowing for more detailed and crisp footage. Its max video frame rate of 120fps also enables smoother slow-motion video capture, providing more creative possibilities for videographers. Furthermore, the Sony a6400 has built-in time-lapse functionality, which is absent in the Sony a7 II. This feature allows users to create stunning time-lapse videos without the need for additional software or equipment.

The Sony a7 II, on the other hand, has limited advantages in its video capabilities compared to the Sony a6400. Its lower max video resolution and frame rate result in less detailed footage and fewer creative options for videographers.

Considering the significant differences in video capabilities, the Sony a6400 is the superior choice for those prioritizing video performance. Its higher max video resolution, frame rate, and built-in time-lapse functionality make it a more versatile and powerful tool for capturing high-quality video content.
