The Sony a7 III outperforms the Sony a6400 with a score of 81 versus 70. Both cameras share similarities as mirrorless cameras, announced in 2018 and 2019 respectively. The a7 III excels with its larger size of 127 x 96 x 74mm and heavier weight of 650g, providing more stability and a more robust build. It also justifies its higher launch price of $2000 compared to the a6400’s $900.

On the other hand, the Sony a6400 has its advantages, such as its compact size (120 x 67 x 60mm) and lighter weight (403g), making it more portable and travel-friendly. While the a7 III takes the lead in overall performance, the a6400 offers a more budget-friendly and compact option for photographers who prioritize portability.

Sony a6400 vs a7 III Overview and Optics

The Sony a7 III outperforms the Sony a6400 in optics with a score of 81/100, a 13-point difference from the a6400’s score of 68/100. Both cameras have 24.2 megapixels, a CMOS sensor, Bionz X processor, and the same shooting speed of 11 and 10 fps, respectively.

The Sony a7 III’s superiority lies in its full-frame sensor size, compared to the a6400’s APS-C sensor. This larger sensor contributes to the a7 III’s higher DXOMARK score of 96, compared to the a6400’s 83. Additionally, the a7 III features image stabilization, an essential factor for capturing sharp, blur-free images, while the a6400 lacks this feature.

The a6400’s main advantage is its Sony E lens mount, which is compatible with a wider range of lenses than the a7 III’s Sony FE mount. This flexibility allows users to expand their lens collection more easily and at a lower cost. Furthermore, the a6400 has a slightly faster shooting speed than the a7 III, which may be beneficial for capturing fast-moving subjects.

The Sony a7 III’s full-frame sensor and image stabilization make it the better camera in terms of optics, providing higher image quality and performance. However, the a6400’s lens compatibility and faster shooting speed may appeal to those who prioritize flexibility and speed in their photography. Ultimately, both cameras have their strengths, and the choice depends on the individual photographer’s needs and preferences.
