Nikon Z30 vs Sony a6400 Overview and Optics

The Nikon Z30 outperforms the Sony a6400 in optics with a score of 72/100 compared to the Sony’s 68/100. Both cameras share several specifications, including an 11fps shooting speed, a CMOS sensor, an APS-C sensor size, and a lack of image stabilization. Despite these similarities, the Nikon Z30 edges ahead in certain aspects.

The Nikon Z30’s higher DXOMARK sensor score of 97, compared to the Sony a6400’s 83, indicates that the Z30 has superior image quality. This camera also has a more advanced processor, the Expeed 6, which contributes to its better performance in terms of optics. Additionally, the Nikon Z30 uses the Nikon Z lens mount, which offers a growing selection of high-quality lenses.

On the other hand, the Sony a6400 has a higher megapixel count at 24.2, compared to the Nikon Z30’s 20 megapixels. This advantage allows for larger prints and more detailed images. The Sony a6400 also uses the Sony E lens mount, which provides a vast array of lenses compatible with the camera.

Despite the Sony a6400’s higher megapixel count and larger lens selection, the Nikon Z30’s superior sensor and processor give it the edge in overall optical performance. The Nikon Z30 is the better choice for those prioritizing image quality and processing capabilities. However, the Sony a6400 may appeal to photographers who require higher resolution images and a broader lens selection.
