Sony a7 II vs a7 III Overview and Optics

The Sony a7 III wins the optics comparison with a score of 81/100, while the Sony a7 II scores 78/100. Both cameras share several specifications, including 24.2 megapixels, a CMOS sensor, the Bionz X processor, full-frame sensor size, and image stabilization. However, there are notable differences that contribute to the a7 III’s higher score.

One significant advantage of the Sony a7 III is its shooting speed. With a speed of 10 frames per second (fps), it doubles the a7 II’s 5 fps. This improvement allows for better action and sports photography, as well as capturing fast-moving subjects.

The a7 III also has a higher DXOMARK score for its sensor, at 96 compared to the a7 II’s 90. This difference indicates better overall image quality, dynamic range, and low-light performance. The Sony a7 III also features the Sony FE lens mount, which provides a wider range of lens options, allowing for greater versatility.

Despite its lower score, the Sony a7 II still offers solid performance in optics. Its 24.2-megapixel resolution, full-frame sensor, and image stabilization ensure quality images. However, it falls short in terms of shooting speed and sensor performance compared to the a7 III.

Comparing the optics of the Sony a7 II and a7 III, the a7 III emerges as the winner due to its faster shooting speed, better sensor performance, and wider lens compatibility. While the a7 II is a capable camera, the a7 III’s superior features make it the better choice for photographers seeking higher performance in optics.
