The Sony a9 II outperforms the Sony a9 by a slight margin, scoring 82/100 compared to the a9’s 80/100. Both cameras share common specifications, such as being mirrorless, having the same launch price of $4500, and similar dimensions. The a9 II’s advantages include a more recent release year (2019) and improved features, which contribute to its higher score.

However, the Sony a9 still has its merits. With a slightly lighter weight of 673g compared to the a9 II’s 678g, it offers a minor advantage in portability. Despite these differences, both cameras deliver impressive performance, making them strong contenders in the mirrorless camera market. The choice between the two ultimately depends on individual preferences and priorities.

Sony a9 vs a9 II Overview and Optics

The Sony a9 II narrowly outperforms the Sony a9 in optics with a score of 82/100 compared to the a9’s 81/100. Both cameras share several specifications, including 24.2 megapixels, a 20 fps shooting speed, a CMOS sensor, a Bionz X processor, full-frame sensor size, a Sony FE lens mount, and image stabilization.

The Sony a9 II’s slight advantage comes from its higher DXOMARK sensor score of 93 compared to the Sony a9’s score of 92. This difference means that the a9 II has slightly better image quality and improved low-light performance. The a9 II’s higher score also reflects its advancements in autofocus performance, which allows for better tracking of subjects and faster focus acquisition.

On the other hand, the Sony a9 does not have any significant advantages over the a9 II in terms of optics. Both cameras share the same core specifications, and the a9 II’s improvements are incremental rather than groundbreaking.

Taking these factors into consideration, the Sony a9 II is the better option for those seeking superior image quality and autofocus performance. However, the difference between the two cameras is minimal, and the Sony a9 remains a strong contender in the full-frame mirrorless camera market. The choice between the two ultimately comes down to individual priorities and budget constraints, as both cameras offer exceptional performance in their respective categories.
