The Sony a6400 outperforms the Sony a7S II with a score of 70/100 compared to 60/100. Both cameras are mirrorless and share similar dimensions, with the a6400 being slightly smaller at 120 x 67 x 60mm and lighter at 403g. The a6400 was released in 2019 and costs $900, while the a7S II was released in 2015 and has a launch price of $3,000.
The a6400’s higher score reflects its more recent technology and better value for money. On the other hand, the a7S II has a larger size (127 x 96 x 60mm) and is heavier at 627g, which may provide a more substantial feel for some users.
Taking into account the specifications and scores, the Sony a6400 is the better choice for those seeking an up-to-date, affordable mirrorless camera. The Sony a7S II may still appeal to those who prefer a heftier camera, despite its lower score and higher price.
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.
The Sony a6400 clearly outshines the Sony a7S II in terms of video capabilities, with a significant difference in scores, 91/100 for the a6400 and 56/100 for the a7S II. Both cameras share some common specifications, such as a maximum video resolution of 4K and video dimensions of 3840 x 2160. However, the a6400 surpasses the a7S II in other aspects, making it the superior choice for video recording.
The Sony a6400 boasts a higher maximum video frame rate of 120fps, compared to the a7S II’s 30fps. This allows for smoother and more detailed slow-motion footage, providing greater creative freedom for videographers. Additionally, the a6400 has built-in time-lapse functionality, which the a7S II lacks. This feature enables users to easily create stunning time-lapse videos without needing additional equipment or software.
On the other hand, the Sony a7S II does not offer any significant advantages in video capabilities over the a6400. Its lower score reflects its inferior performance in comparison to the a6400. The lack of time-lapse functionality and a lower frame rate make the a7S II a less appealing option for those prioritizing video recording.
In comparing the video capabilities of the Sony a6400 and the Sony a7S II, the a6400 stands out as the superior choice, offering a higher video score, a greater maximum video frame rate, and built-in time-lapse functionality. The a7S II fails to provide any substantial advantages over the a6400 in this regard. Therefore, the Sony a6400 is the recommended option for those seeking a camera with exceptional video recording capabilities.
The Sony a6400 emerges as the winner in the features category, scoring 81 out of 100 points, compared to the Sony a7S II, which scores 57 points. Both cameras share several specifications, such as a 3-inch screen size, flip screen functionality, and the absence of GPS. Additionally, both cameras offer WIFI connectivity, allowing users to transfer images wirelessly.
The Sony a6400 outshines the a7S II in certain aspects. Firstly, it has a touchscreen feature, which makes it easier to navigate through menus and settings. This feature is absent in the a7S II. Secondly, the a6400 includes Bluetooth connectivity, allowing for seamless pairing with compatible devices. The a7S II lacks this feature, limiting its connectivity options.
On the other hand, the Sony a7S II has a higher screen resolution of 1,228,800 dots, compared to the a6400’s 921,600 dots. This means that the a7S II provides a clearer and more detailed display, which can be helpful for photographers when reviewing images.
Taking all these factors into consideration, the Sony a6400 has a clear advantage in terms of features, with a touchscreen and Bluetooth connectivity. However, the a7S II offers a higher screen resolution, which can be beneficial for those who prioritize image clarity on the camera’s display. Ultimately, the choice between these two cameras depends on the individual’s preferences and priorities in terms of features and functionality.
The Sony a6400 outperforms the Sony a7S II in storage and battery with a score of 37/100 compared to 21/100. Both cameras have a single memory card slot and accept SD/SDHC/SDXC and Memory Stick Duo cards. However, the a6400 is compatible with UHS-I cards, while the a7S II also supports Pro Duo and Pro-HG Duo cards.
The a6400 has a battery life of 410 shots, which is superior to the a7S II’s 370 shots. Both cameras use the NP-FW50 battery type. The a6400 has the advantage of USB charging, which the a7S II lacks.
