What are the biggest differences between the Nikon Z6 III and the Sony A7 IV?

The Nikon Z6 III and Sony A7 IV belong to the latest generation of full-frame mirrorless cameras, but each takes a different technical approach. Nikon introduces a stacked sensor in the mid-range segment with the Z6 III, giving you ultra-fast readout, smooth autofocus and improved video performance. Sony focuses with the A7 IV on high resolution and a versatile autofocus, making it a solid all-rounder for both photography and video.

The Nikon Z6 III offers a stacked sensor for fast readout and impressive video capabilities, including 6K RAW recording. The electronic viewfinder is larger and sharper than the Sony's, and image stabilisation performs slightly better. The Sony A7 IV excels with its higher resolution, versatility and longer battery life. Both cameras offer a dual card system, modern autofocus and extensive video features. Your choice depends on what matters most: speed and innovative video with Nikon, or flexibility, resolution and proven all-round performance with Sony.

What are the advantages and disadvantages of the Sony A7 IV?

Advantages

  • High resolution of 33 megapixels, capturing a great deal of detail and giving more flexibility during post-processing or cropping.
  • Versatile autofocus with real-time tracking for people, animals and birds; suitable for a wide range of photography genres.
  • Strong all-round performance: excellent for both photo and video, with 4K 60p in 10-bit.
  • Compact and relatively lightweight design, easy to take along for travel or long photography sessions.
  • Battery life is above average, ideal for long days of shooting without needing to swap batteries often.
  • Extensive lens choice due to the large and mature Sony E-mount ecosystem.
  • Dual memory card slots (CFexpress A / SD UHS-II) for fast storage and backup while working.

Disadvantages

  • No stacked sensor, meaning readout speed and rolling shutter with fast action are less capable than with the Nikon Z6 III.
  • Maximum burst rate of 10 frames per second is lower than Nikon, which can be limiting for fast-action subjects.
  • 4K video at 60p is only possible with a slight crop; those seeking full-frame 4K 60p will not find it in this camera.
  • The tiltable screen is less sturdy than some competitors, especially with intensive use.
  • Menus and settings are extensive and require getting used to, especially for those switching from another brand.
