The Sony a9 outshines the Sony a6600 with a score of 80/100 compared to 75/100. Both cameras are mirrorless and share similarities in specifications. They were released in 2017 and 2019 respectively, with the a9 being the more expensive option at $4500, while the a6600 costs $1200.

The Sony a9 excels with its superior performance and features, justifying its higher price. On the other hand, the Sony a6600 has its advantages, such as being lighter at 503g compared to the a9’s 673g, and having a smaller body size of 120 x 67 x 69mm versus the a9’s 127 x 96 x 63mm.

When considering these factors, the Sony a9 is the better camera for professionals who require top-notch performance, while the Sony a6600 is a more affordable and portable option for casual users or beginners.

Sony a6600 vs a9 Overview and Optics

The Sony a9 wins in optics with a score of 81/100, compared to the Sony a6600’s 76/100. Both cameras share several specifications, such as a 24.2-megapixel resolution, CMOS sensor type, Bionz X processor, and image stabilization. Additionally, they both have Sony lens mounts: the a6600 uses the Sony E mount, while the a9 utilizes the Sony FE mount.

The Sony a9’s higher score is due to its superior shooting speed and sensor performance. With a shooting speed of 20 frames per second, the a9 is faster than the a6600’s 11 frames per second. The a9’s DXOMARK sensor score is 92, which is significantly higher than the a6600’s score of 82. Furthermore, the a9 has a full-frame sensor size, while the a6600 has an APS-C sensor size. This difference in sensor size contributes to the a9’s better overall image quality.

On the other hand, the Sony a6600 is not without its merits. The camera’s APS-C sensor size and Sony E lens mount make it compatible with a wider range of lenses, including those designed for crop-sensor cameras. This compatibility can be advantageous for users who already own or plan to invest in these lenses.

Taking all factors into consideration, the Sony a9’s superior shooting speed, sensor performance, and full-frame sensor size make it the better choice for photographers seeking top-tier optics. However, the Sony a6600 may be a more suitable option for those who prioritize lens compatibility and affordability, without compromising on image quality.

Sony a6600 vs a9 Video Performance

The Sony a6600 outperforms the Sony a9 in video capabilities, scoring a remarkable 91 out of 100, while the a9 falls behind with a score of 56. Both cameras boast a 4K maximum video resolution and 3840 x 2160 video dimensions, providing sharp and detailed footage. However, the a6600 demonstrates superiority in other aspects.

The a6600 excels with a higher maximum video frame rate of 100fps, double that of the a9’s 30fps. This advantage allows the a6600 to capture smoother motion, making it ideal for recording fast-paced action or for creating slow-motion effects in post-production. Furthermore, the a6600 comes with built-in time-lapse functionality, offering creative options for photographers and videographers to showcase the passage of time in their projects.

Despite its lower score, the a9 still maintains quality video output with its 4K resolution and 3840 x 2160 dimensions. However, the camera’s lower frame rate and lack of built-in time-lapse features limit its video capabilities compared to the a6600.

Considering the significant differences in video scores and features, the Sony a6600 emerges as the superior choice for those prioritizing video capabilities. Its higher frame rate and built-in time-lapse function provide greater creative flexibility, while its 4K resolution and video dimensions match those of the a9. While the a9 still offers quality video output, it falls short in comparison to the a6600’s advanced video performance.
