The Sony a7 III emerges as the winner with a score of 81, while the Sony a7R II trails behind at 70/100. Both cameras are mirrorless and have similar dimensions, with the a7 III measuring 127x96x74mm and weighing 650g, and the a7R II measuring 127x96x60mm and weighing 625g.

The a7 III outperforms the a7R II due to its more recent release in 2018, as opposed to the a7R II’s 2015 release, and its lower launch price of $2000 compared to the a7R II’s $3198. This makes the a7 III a more cost-effective and updated option for consumers.

On the other hand, the a7R II has a slight advantage in terms of weight, being 25g lighter than the a7 III. This difference, however, may not significantly impact the overall experience for users.

Taking these factors into account, the Sony a7 III is the better option for its updated features and lower price, while the a7R II’s only advantage lies in its marginally lighter weight.

Sony a7 III vs a7R II Overview and Optics

The Sony a7 III and Sony a7R II both receive an optics score of 81/100, indicating no clear winner in this category. These cameras share several specifications, including a CMOS sensor, Bionz X processor, full-frame sensor size, Sony FE lens mount, and image stabilization.

The Sony a7 III has a 24.2-megapixel resolution and a shooting speed of 10 frames per second, making it a strong choice for fast-paced photography. Its DXOMARK sensor score is 96, which is slightly lower than the a7R II but still impressive. The a7 III’s lower megapixel count and faster shooting speed make it well-suited for capturing action shots and sports photography.

On the other hand, the Sony a7R II boasts a higher resolution with 42.4 megapixels, allowing for more detailed images. However, its shooting speed is slower at 5 frames per second, which may not be ideal for capturing fast-moving subjects. The a7R II has a DXOMARK sensor score of 98, which is slightly higher than the a7 III, indicating better overall image quality. The a7R II is better suited for photographers who prioritize image detail and resolution over speed.

Both cameras have their strengths and weaknesses, with the a7 III excelling in fast-paced photography and the a7R II providing superior image detail. Ultimately, the choice between these two cameras depends on the specific needs and preferences of the photographer.
