Key Differences Between Nikon Z7 II and Sony A7 IV

  • Body and Handling Comparison

The Nikon Z7 II and Sony A7 IV have similar weights and dimensions, though the Sony is slightly lighter at 658g Vs. 705g. Both cameras offer excellent build quality and weather sealing.

In terms of handling, the deeper Nikon grip provides a bit more secure hold. But the Sony is no slouch either. Those with larger hands may prefer the Z7 II ergonomics.

Button placement and menus are quite different between the two brands. Nikon offers more dedicated controls while Sony utilizes a more minimalist approach.

If you’re already used to one brand’s interface, switching to the other will require some relearning. New users however should not find major issues adapting to either camera.

  • Autofocus Performance

For still photography, both cameras offer lightning fast autofocus that works great for all kinds of shooting scenarios. The Nikon Z7 II relies on its hybrid phase/contrast detect system with 493 points. The Sony A7 IV uses 759 phase and 425 contrast points.

In practice, you can expect reliable subject tracking and accurate eye/face/body detection from either model. The Sony does have an edge for video use, offering more confident continuous AF for 4K footage. But the Nikon is no slouch either.

For those needing the best video autofocus, the Sony A7 IV is the safer choice. But both are perfectly capable for casual and vlogging use.

  • Image Quality Comparison

With their high resolution full frame sensors, both the Z7 II and A7 IV are capable of capturing stunning images with wide dynamic range. However, there are some key differences.

The Nikon has a higher resolution 45.7MP sensor compared to 33MP on the Sony. This gives the Z7 II the edge for situations requiring extensive cropping or giant prints.

However, the newer Sony sensor offers improved dynamic range and high ISO noise performance. At lower ISOs, there is little difference. But as you go higher, the A7 IV shows around a 1 stop advantage for maintaining detail in shadows and minimizing noise.

For general shooting purposes, most users would be hard pressed to see major differences between the sensors. But those needing to push exposure limits may appreciate the Sony’s extra latitude.

  • Video Quality

Both cameras offer premium quality video features including:

  1. 4K up to 60 fps
  2. 10-bit internal recording
  3. Flat color profiles (N-Log and S-Log3) for maximum grading flexibility

Footage quality is excellent from both cameras. However, the Sony A7 IV pulls further ahead for dedicated video use thanks to features like its new 10-bit XAVC HS codec.

The oversampled and line skipped Super 35 crop mode on the A7 IV also helps optimize 4K video quality. Plus, Sony’s latest image processor and improved AF make the A7 IV better suited for serious vlogging and filmmaking.

That said, the Nikon Z7 II is no slouch for hybrid shooters needing occasional high quality 4K footage. Just don’t expect the same robust video toolkit offered in the A7 IV.

  • Lenses and Accessories

One of the most important considerations with any mirrorless camera is the lens ecosystem. Both Nikon and Sony offer a solid and expanding catalog of high performance options.

For the Z7 II, Nikon Z-mount lenses are the way to go. Nikon offers a range of premium f/1.8 primes along with f/4 zooms covering wide angle to telephoto needs. Using an FTZ adapter also opens up access to a huge array of F-mount lenses.

On the Sony side, choices include G-Master f/1.4 primes and f/2.8 zooms along with more affordable options from Sigma and Tamron. Adapters are also available for using Sony A-mount and other lens brands.

Each system offers excellent native lens support along with the flexibility of adapters for expanding creative options. For most enthusiasts and pros, either camera will work great.

  • Price and Value Comparison

The Nikon Z7 II originally retailed for $2,999 body only or $3,999 with a 24-70mm kit lens. The Sony A7 IV launched at $2,499 body only.

Given its lower launch price along with improved autofocus and video specs, the A7 IV offers better overall value, especially for hybrid shooters. However, the Z7 II remains a highly compelling choice for photographers focused mainly on stills.

Both cameras offer substantial upgrades over earlier models. The choice ultimately comes down to your personal shooting needs and brand preferences.
