Sony a7 IVvsNikon ZR: Which Camera Should You Buy?
Both are full-frame mirrorless bodies with two card slots, in-body stabilization claims, log profiles and similar dust-and-drip sealing. The split is purpose: the Sony a7 IV is built around stills, with a 33 MP sensor and a real electronic viewfinder, while the Nikon ZR is a video-first body with 6K capture, internal raw and a much larger rear screen.

Stills resolution and viewfinder
The Sony a7 IV resolves 33 MP against the Nikon ZR's 24.5 MP. That extra pixel count is the difference between comfortable cropping and tight cropping — useful for wildlife, event work and anyone who delivers prints. The Sony also carries a 3.69 M-dot electronic viewfinder, which the ZR does not offer at all.
Composing on a finder rather than a rear panel matters for handheld work in bright light and for steadying long lenses against your face. If most of your shooting is photographs, these two facts alone settle the comparison.
Video: resolution, frame rates and raw
The Nikon ZR records 6K and hits 119.88 fps in 4K, and it can capture raw internally. The Sony a7 IV tops out at 4K and has no raw recording at all, internally or externally, with its HDMI output limited to 10-bit 4:2:2. For anyone grading footage or delivering to a client who wants flexibility in post, that is a hard ceiling.
There is a caveat on the Sony's 4K 60p: it only works in Super35mm crop, so full-width 4K stops at 30p. Cropping narrows your field of view and changes how wide lenses behave. The ZR avoids that compromise entirely.
Autofocus subject detection
Both cameras detect humans, animals and birds. The Nikon ZR adds cars, trains, airplanes and motorcycles to that list.
If you shoot aviation, motorsport or railways, the ZR will track those subjects without you fighting the camera. Everyone else can treat autofocus as a tie and decide on other grounds.
Burst shooting: mechanical vs electronic
The Sony a7 IV shoots 10 fps with the mechanical shutter, dropping to 6 fps for lossless or uncompressed RAW. The Nikon ZR reaches 20 fps electronically — twice the rate — but Nikon has not published a mechanical figure, and pre-burst capture is listed at 0 s, so there is no rolling buffer before you press the shutter.
Higher frame rates help with fast, unpredictable movement. The Sony's mechanical option avoids the rolling-shutter distortion that electronic shutters can show on moving subjects.
Screen, size and battery
The Nikon ZR's rear panel is 4 inches at 3.07 M dots, against the Sony's 2.95-inch 1.04 M-dot screen. A larger, denser display makes manual focus and menu work easier, especially outdoors. The ZR is also the lighter and shallower body, and slightly shorter, while the Sony is marginally narrower.
Battery life is the Sony's strong point: 580 shots per charge on the LCD, 520 through the finder. Nikon has not published a CIPA rating for the ZR, so video shooters should plan on spare cells. Both charge over USB-C, and both have headphone ports.
Which is best for sports and action?
The Nikon ZR's 20 fps electronic burst and its expanded subject list — including cars, trains, airplanes and motorcycles — make it the better tool for fast, vehicle-based action. The Sony a7 IV's 10 fps mechanical burst is steadier and free of electronic-shutter distortion, which suits ball sports and other subjects where shape matters more than raw speed.
One thing neither camera answers from published specs: both list sensor readout speed as not published, so rolling-shutter behaviour in electronic mode is unverified for each.
The Verdict
Buy the Sony a7 IV if photographs come first and you want 33 MP of cropping room plus a proper electronic viewfinder and stronger battery life. Buy the Nikon ZR if you shoot video seriously and need 6K, 4K at 119.88 fps and internal raw without a crop penalty. Buy the Nikon ZR if you photograph cars, trains, planes or motorcycles and want the camera to track them. Buy the Sony a7 IV if you want the mechanical shutter and the more compact width.

FAQ
Does the Sony a7 IV shoot raw video?
No. The Sony a7 IV has no internal or external raw recording, and its HDMI output is limited to 10-bit 4:2:2. The Nikon ZR records raw internally.
Is the Nikon ZR good for photography?
It can be, but it has no electronic viewfinder and its 0 M-dot viewfinder spec means you compose on the 4-inch rear screen. The Sony a7 IV offers a 3.69 M-dot finder and 33 MP of resolution.
Can the Sony a7 IV shoot 4K at 60p without a crop?
No. 4K 60p is only available in Super35mm crop on the Sony; full-frame 4K tops out at 30p. The Nikon ZR reaches 119.88 fps in 4K.
How many memory card slots do these cameras have?
Both have two card slots. Neither figure differs, so it is not a deciding factor between them.
Which camera is lighter?
The Nikon ZR at 630 g, against 658 g for the Sony a7 IV. The ZR is also noticeably shallower, which helps in small bags.
