About the Nikon Z7ii and Sony a7III

Nikon unveiled the Z7 II in 2020 as the successor to its flagship high-resolution full-frame mirrorless camera. Rather than a complete overhaul, the Z7 II represents a refined version of its predecessor. We were particularly fond of the original Z7, and this new model builds upon its already successful formula. Retaining the 45.7MP full-frame BSI sensor, the Z7 II elevates its performance with the inclusion of dual processors, a notable upgrade from the single processor found in its predecessor. While the improvements may not be revolutionary, they contribute to an enhanced shooting experience and reinforce the camera’s reputation.

The Sony a7 III features which was launched in 2018 is a 24.2-megapixel full-frame sensor with 5-axis in-body image stabilization, and an advanced hybrid autofocus system with 693 focus points. It can shoot 4K video at up to 30 frames per second, also has a weather-sealed body, and utilizes Sony’s E-mount. The Sony a7 III is designed for photographers who value a well-rounded camera with excellent low-light performance, fast and accurate autofocus, and high-quality video capabilities.

Design and Build Quality

When it comes to design and build quality, both the Nikon Z7ii and Sony a7III are top-notch. The Z7ii features a rugged, weather-sealed magnesium alloy body that feels solid and durable in the hand. It also has a large, comfortable grip that makes it easy to hold for extended periods of time.

The Sony a7III, on the other hand, features a slightly smaller, lighter body that’s also weather-sealed and made of magnesium alloy. It has a comfortable grip, but some users have noted that it can feel a bit cramped for those with larger hands. Overall, both cameras are well-built and should stand up to years of heavy use. However, if you prioritize a larger grip and more comfortable handling, the Nikon Z7ii may be the better choice.

Sensor and Image Quality

The heart of any camera is its sensor, and both the Nikon Z7ii and Sony a7III have impressive sensors that deliver excellent image quality. The Z7ii features a 45.7-megapixel back-illuminated CMOS sensor, while the a7III has a 24.2-megapixel back-illuminated CMOS sensor.

While the Z7ii has a higher resolution sensor, this doesn’t necessarily mean it’s the better choice for everyone. If you shoot in low light or prioritize high-speed performance, the a7III’s lower resolution sensor may actually be a better fit. This is because larger pixels on the sensor can lead to better low-light performance and faster readout speeds.

In terms of image quality, both cameras are capable of capturing stunning, detail-rich photos with accurate colors and impressive dynamic range. However, if you’re a professional photographer who frequently prints large format images, the higher resolution of the Z7ii may be more desirable.


Both the Nikon Z7ii and Sony a7III feature advanced autofocus systems that are highly capable and accurate. The Z7ii has a hybrid AF system with 493 phase-detection points and 90% coverage of the frame, while the a7III has a hybrid AF system with 693 phase-detection points and 93% coverage of the frame. In real-world use, both cameras perform exceptionally well, with fast, accurate autofocus even in low light. However, some users have noted that the Sony a7III’s autofocus system may be slightly faster and more reliable overall.

Video Features

If you’re a videographer, both the Nikon Z7ii and Sony a7III have plenty to offer. The Z7ii can shoot 4K UHD video at up to 60p with full pixel readout and no pixel binning, as well as 10-bit N-Log and HDR (HLG) support. It also has a 10-bit HDMI output for external recording. The a7III, meanwhile, can shoot 4K UHD video at up to 30p with full pixel readout and no pixel binning, as well as S-Log3 and HLG support. It also has a 8-bit HDMI output for external recording.

Nikon Z7ii Vs Sony a7III

While both cameras offer impressive features, there are a few key differences:

  • Sensor resolution: The Nikon Z7II has a higher resolution sensor compared to the Sony a7 III, which can result in more detailed images, especially when cropping or printing large formats.
  • Autofocus system: The Sony a7 III has a more advanced autofocus system with 693 focus points, providing better coverage across the frame and faster subject tracking.
  • Lens mount: The Nikon Z7II uses Nikon’s Z-mount, while the Sony a7 III uses Sony’s E-mount. The lens selection and ecosystem for each mount may influence a photographer’s decision, considering their existing lens collection or availability of specific lenses.
  • Video capabilities: While both cameras can shoot 4K video, the Nikon Z7II can capture 4K at up to 60 frames per second, offering smoother video playback. The Sony a7 III, on the other hand, has slightly more limited video features but still provides excellent video quality.
