Should you buy the Nikon Z6 III or the Sony A7 IV?
Buy the Nikon Z6 III if you also shoot serious video or fast action: it has a partially stacked sensor with 20 fps electronic bursts, 6K/60p RAW video and less rolling shutter. Buy the Sony A7 IV if you want a higher-resolution 33 MP sensor, longer battery life with the viewfinder, a more established lens ecosystem and the autofocus that reviewers call more reliable. For event photography, both have two card slots, so autofocus confidence and lenses usually decide.

Sony A7 IV
The Sony A7 IV is the established all-rounder. Its 33 MP sensor leaves more room to crop than the Z6 III's 24.5 MP, and reviewers credit it with strong battery life and a deep lens range. See the A7 IV deals.
Strengths: higher resolution, mature autofocus, lens range and battery life.
Trade-offs: slower bursts and no RAW video, and its 4K 60p mode uses a crop.
Nikon Z6 III
The Nikon Z6 III is the newer design, with a partially stacked sensor that allows 20 fps electronic bursts, 6K RAW video and less rolling-shutter distortion. RTINGS ranks it better overall, while noting the Sony's higher resolution. See the Nikon Z6 III listing, or check today's deals.
Strengths: faster sensor, serious video specifications and strong subject recognition.
Trade-offs: a smaller lens range than Sony and lower resolution.
Which camera suits which photographer?
| If you want | Best fit | Why |
|---|---|---|
| Hybrid photo and video | Nikon Z6 III | 6K/60p RAW and less rolling shutter |
| Event photography | Either | Both have dual slots, and the Z6 III bursts faster |
| The most reliable autofocus and lens choice | Sony A7 IV | RTINGS rates its autofocus more reliable |
| Cropping room | Sony A7 IV | 33 MP against 24.5 MP |
| Longer battery life | Sony A7 IV | Better with the viewfinder, per PhotographyLife |
What should you check before choosing?
- Your lenses. A body is only as useful as the lenses available for it. Sony's E mount has a larger range from Sony and third-party makers, and Nikon's Z mount is growing. Price the lenses you actually need before comparing bodies.
- Your subjects. Fast or unpredictable subjects favour the Z6 III's faster sensor. Still subjects and heavy cropping favour the A7 IV's 33 MP.
- Your video needs. If you record RAW or want 4K at 120p, only the Z6 III offers it. If 10-bit 4K is enough, the A7 IV is capable.
- Rolling shutter. Electronic-shutter bursts of fast-moving subjects show more distortion on the A7 IV, according to RTINGS.
- Your budget. Prices change often, so compare current listings for both bodies and for the kit lens.
Which lens kit comes with each camera?
The A7 IV is commonly sold with the FE 28-70mm f/3.5-5.6 OSS kit lens, and the Z6 III is sold in kits with Nikon Z zoom lenses. Kit lenses are convenient, but a fast prime or a constant-aperture zoom often improves results more than a body upgrade. See the lens guides linked below for good pairings.
