Nikon Z7 II vs Sony A7 IV
Every spec below is quoted from the makers' official pages — where a figure isn't published we say so rather than guess. Sizes are drawn at true relative scale from published dimensions, and the bag-fit row is computed against our measured bag catalog.
The 3 biggest published differences
- Resolution (MP): the Z7 II leads at 45.7 million (effective) vs the A7 IV's 33.
- In-body stabilisation: the A7 IV leads at 5.5 stops vs the Z7 II's 5-axis image sensor shift; up to 5.0 stops (five stops in up to five directions with compatible Z lenses).
- Weight (body): the A7 IV leads at 658 g vs the Z7 II's 705 g.
