The Sony a7 IV comes out on top with a score of 84/100, while the Sony a6400 trails behind at 70/100. Both cameras share similarities as mirrorless systems, but there are notable differences to consider.

In terms of commonalities, both cameras were announced in their respective years, with the a6400 in 2019 and the a7 IV in 2021. They also share a similar launch price, with the a6400 at $900 and the a7 IV at $2499.

The a7 IV outshines the a6400 with a higher score and more recent release, providing users with updated technology and features. Additionally, its larger size (131 x 96 x 80mm) and weight (659g) may offer a more substantial feel to users who prefer a heftier camera.

On the other hand, the a6400 shines in its compact size (120 x 67 x 60mm) and lighter weight (403g), making it a more portable option for on-the-go photography. However, its lower score and older release date may make it less appealing to users seeking the latest technology.

Both cameras have their strengths and weaknesses, but the Sony a7 IV ultimately takes the lead in terms of overall performance and features. The a6400 still holds value as a compact and more affordable option for those prioritizing portability.

Sony a6400 vs a7 IV Overview and Optics

The Sony a7 IV outperforms the Sony a6400 in optics, scoring 85/100 compared to the a6400’s 68/100. Both cameras share some common specifications, such as a CMOS sensor, and compatibility with Sony’s E and FE lens mounts. They also have similar shooting speeds, with the a6400 at 11 frames per second and the a7 IV at 10 frames per second.

The a7 IV is superior in several aspects. It features a higher megapixel count of 33, allowing for more detailed images compared to the a6400’s 24.2 megapixels. The a7 IV also has a more advanced Bionz XR processor, which contributes to improved image processing and overall performance. Additionally, the a7 IV boasts a full-frame sensor, which provides better low-light performance and a wider dynamic range than the a6400’s APS-C sensor. The full-frame sensor also contributes to the a7 IV’s higher DXOMARK score of 97, compared to the a6400’s score of 83. Lastly, the a7 IV includes image stabilization, a feature absent in the a6400, making it more suitable for handheld shooting and low-light situations.

The a6400 does have a faster shooting speed of 11 frames per second compared to the a7 IV’s 10 frames per second, which may give it a slight advantage in capturing fast-moving subjects. However, this advantage is minimal in the context of the a7 IV’s overall better optical performance.

Considering the differences in optics, the Sony a7 IV is the superior camera. Its higher megapixel count, advanced processor, full-frame sensor, and image stabilization make it a better choice for photographers seeking top-notch image quality and performance. The a6400’s faster shooting speed does not outweigh the benefits offered by the a7 IV’s superior optics.
